How do i solve the equation (-7,1),(7,8)?
How do I solve the equation?
You don't have an equation. You have two points. You need to
determine the equation for the line that passes through those points.
You obtain the slope m using (y2 - y1) / (x2 - x1)
m = (8 - 1) / (7 - (-7))
m = 7 / 14
m = 1/2
This gives y = 1/2 x + b. Plug in either of the
co-ordinate pairs you were given and solve for b.
y = 1/2 x + b
8 = 1/2(7) + b
8 = 3.5 + b
4.5 = b
So, the equation is y = 1/2 x + 4.5
