You will NOT substitute values for x and y. That is because the point-slope form is only used as a tool in finding an equation.

The rate is your slope in the problem. What will we look for in the problem? I will tell you that In the examples worked in this lesson, answers will be given in both forms. If all of your experts are half as good, you have a great thing going here.

You can also check your equation by analyzing the graph. Transforming the slope-intercept form into general form gives Parallel and Perpendicular There is one other common type of problem that asks you to write the equation of a line given certain information.

If we re-write in slope-intercept form, we will easily be able to find the slope. Not only did you answer my questions, you even took it a step further with replying with more pertinent information I needed to know.

How do you know which one is the right one? Is your graph rising from left to right? What is your answer? Write the equation of the line that passes through the points 7, -3 and 7, 0.

Real World Problems When you have a real world problem, there are two things that you want to look for! All you need to know is the slope rate and the y-intercept. Freshfield, Liverpool, UK This expert is wonderful. Example 2 demonstrates how to write an equation based on a graph.

Inner-city high school substitute teacher. Since you have a point and a slope, you should use the point-slope form of a line.

This type of problem involves writing equations of parallel or perpendicular lines. Although the numbers are not as easy to work with as the last example, the process is still the same.

It is nice to know that this service is here for people like myself, who need answers fast and are not sure who to consult. Two of those are: Write an equation in slope intercept form given the slope and y-intercept. Calculate the slope from the y-intercept to the second point.

Thank you so much!!!! You have a positive slope. Credentials confirmed by a Fortune verification firm. Traffic on JustAnswer rose 14 percent As we have in each of the other examples, we can use the point-slope form of a line to find our equation.

If is parallel to and passes through the point 5, 5transform the first equation so that it will be perpendicular to the second. You may be wondering why this form of a line was not mentioned at the beginning of the lesson with the other two forms. It is not a way to present your answer.

This is the site I will always come to when I need a second opinion. Plug those values into the point-slope form of the line: Those have x and y variables in the equation.

JustAnswer in the News: Yes, it is rising; therefore, your slope should be positive!1. Write an equation of a line perpendicular to line AB below in slope-intercept form that passes through the point (7, 6).

Line AB is shown. A is at 0, /5(9). Equations of lines come in several different forms. Two of those are: slope-intercept form; where m is the slope and b is the y-intercept. general form; Your teacher or textbook will usually specify which form you should be using.

In the examples worked in this lesson, answers will be given in both forms. Write the equation for a line that has a slope of -2 and y-intercept of 5. NOTES: I substituted the value for the slope (-2) for m and the value for the y-intercept (5) for b.

The variables x and y should always remain variables when writing a linear equation. Question Write the slope-intercept form of the equation of the line shown in the graph.

Please show all of your work. Please show all of your work. (-6, -2) (4, 3). A line has a slope of negative 3/4 and goes through the point 0 comma 8. What is the equation of this line in slope-intercept form? So any line can be represented in slope-intercept form, is y is equal to mx plus b, where this m right over here, that is of the slope of the line.

Write an equation in slope -intercept form of the line having the given slope and y-intercept or given Write an equation in slope -intercept form for each line shown or described. $(5 y = 5 $(5 Write an equation in slope -intercept form for a line containing (4, 2) that is parallel to the line .

DownloadWrite an equation in slope intercept form of the line shown
