Question

What is the equation, in slope-intercept form, of a line that passes through the points (1,8) and (-2,2)?

Answer 1

Answer:

y=2x+6

Step-by-step explanation:

You can first set up the equation in point slope form and plug in your two points to solve for slope

y-y=m(x-x)

8-2=m(1+2)

6=m(3)

m=2

Then plug in one point into the point slope form equation to make it into slope intercept form

y-8=2(x-1)

y=2x-2+8

y=2x+6
