How do you write the equation in slope intercept form given slope -4/5, passing through (5,-5)?
the slope intercept equation is y = mx + b
Substitute the values of (x,y) from the point to solve for b.
The slope is m in the y=mx +b form ( Think m mountain ski slope)
The y intercept is b ( think beginning)
Substituting the values ( 5,-5) into the equation gives.
