Write the equation of the line passing through the points (-1, 2) and (3, 4)
A)
y = 2x - 2
B)
y = 2x - 10
+
C)
y =1/2x + 5/2
D) y=1/2x-5/2

D

Step-by-step explanation:

y_2 - y_1 / x_2 - x _1

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

y +4 = 1/2 (x + 3) distributive property

y + 4 = 1/2x + 1.5

y= 1/2x - 5/2 subtraction (you subtract 4 from both sides) (-5/2 = -2.5)

therefore your equation is y = 1/2x - 5/2

hope this helps :)

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
