Question 222140: write an equation for each line
1. y-intercept of -2.1, x-intercept of 3.5
2. through (1.2,5.1), x-intercept of 3.7 Answer by solver91311(24713) (Show Source):
First realize that the -intercept is the value of the -coordinate of the point where the line intersects the -axis. That is to say, if the -intercept is -2.1, then the point is a point on the line. Likewise, -intercepts represent a point where is the -intercept.
Now you can see that you have two problems where you are given two points and need to derive the equation of the line passing through the two points. Use the two-point form of the equation of a line:
where and are the coordinates of the given points.
