Question

Which equation represents the line passing through the points (2, -2) and (-5, 12)?

Answer 1

use the slope formula and then y=mx+b

Answer 2

first you need to find the slope

the slope for is \[y _{2}-y _{1} \over x _{2} - x _{1}\]

the slope in this case is -2

so for the y intercept it is -2

so the equation is

y= -2x -2
