Just doing some review, and I keep getting the wrong answer. Can someone explain this for me please?
The equation of the straight line through the points (-2; 1) and (2; 3) is
Book says the correct answer is 2y = x + 4
What are the steps to get 2y = x + 4 ???
The Attempt at a Solution
Here is what I did:
Slope = 1/2
so y =1/2x + c
taking 2 points, 2,3 as in x and y
so y=1/2x + 2.75
Im so lost....:(
