equation parallel to x-2y=8 containing (-1,9)
determine the equation for the line parallel to x-2y=8
and containing (-1,9) write answer in slope intercept form
Find the slope.
x - 2y = 8
-2y = -x + 8
y = 1/2 x - 4
y = mx + b
b = y - mx
Solve for the y-intercept, using the specified point.
b = 9 - (1/2 * -1)
b = 9 + 1/2
b = 9 1/2
The equation is y = 1/2 x + 9 1/2
