Since you are writing this in slope-intercept equation you will want to isolate the y. Therefore move the -8x over making it into -2y=8x+10. Then simply divide by the -2. And your equation will be y=-4x-5.
90cm on of the each f and g
First line going down is y=2x+4
Second one going / this way is y=-1x-1
