y=$\frac{5}{2}$x-5 m=$\frac{5}{2}$ y-intercept=-5

Work Step by Step

First isolate y in the given equation. 5x-2y=10 5x-2y+2y=10+2y 5x=10+2y 5x-10=10-10+2y 5x-10=2y 2y=5x-10 $\frac{2y}{2}$=$\frac{5x-10}{2}$ y=$\frac{5}{2}$x-$\frac{10}{2}$ y=$\frac{5}{2}$x-5 Now that the equation is in the form of y=mx+b you can see than m=$\frac{5}{2}$ and y-intercept=-5
