Find an equation for the line that passes through the points (-1,2) and (5,5)

y = 1/2x +5/2

Step-by-step explanation:

First we find the slope

m = (y2-y1)/(x2-x1)

   = (5-2)/(5- -1)

   = (5-2)/(5+1)

   = 3/6

 1/2

We have the slope intercept form of a line

y = mx+b where m is the slope and b is the y intercept

y = 1/2 x+b

Substitute a point into the equation

2 = 1/2 (-1) +b

2 = -1/2 +b

add 1/2 to each side

4/2 + 1/2 = b

5/2 = b

y = 1/2x +5/2

2 5/8 is the final answer! : )

i think its a and d
