Slope Reference Equation
-5x%2B7y=-1
7y=-1%2B5x
y=-1%2F7%2B%285%2F7%29x
y=%285%2F7%29x-1%2F7
-
Slope is 5%2F7.
The slope for the equation you want is m%2A%285%2F7%29=-1.
highlight_green%28m=-7%2F5%29


Intercept Reference Equation
x-3y=-8
-3y=-x-8
y=x%2F3%2B8%2F3
-
This shows y-intercept highlight_green%288%2F3%29.


Equation fitting the specified description:
highlight%28y=%28-7%2F5%29x%2B8%2F3%29
