Question

What is the y-intercept of the line that passes through the points (3,7) and (-2,-3)?

A.) (1,0)
B.) (0,4)
C.) (0,1)
D.) (0,-4)

Answer 1

There's probably and easier way to do this, but if you set up an equation in point slope form and input 0 for x that should work. The slope is (-3-7)/(-2-3)= 2, so an equation would be y=2(x-3)+7. y=2(0-3)+7  =  y=-6+7= 1, and of course the x coordinate is 0, so (0, 1) is the y int.
