Question

What is the equation of a line in slope intercept form that passes through the points (-4,3) and (-2,4)

Answer 1

First find slope.

slope=change in y/change in x (y2-y1/x2-x1)

slope=4-3/-2-(-4)=1/2

Now we need to find the x intercept.

y=mx+b

3=1/2(-4)+b

b=5

So the equation is y=1/2x+5.
