Write the equation of a line which contains the point (2,4) and (-2,2)

y = -2x + 2

y = 2x + 4

y = ½x + 3

y = -4x + 2

The slopes has to be (2-4)/(-2-2)=-2/-4

But that's not one of the answers so what do i DO?

-2/-4 = 1/2 There is no line with a slope of 1/2??

Try a point in each of them to see if it makes a true equation.

this is what the problem gives me:
