x=7 and y=4
Solving by the elimination method: x = 7 and y = 2
-8x + 4y = 28 Add 8x to each side: 4y = 8x + 28 Divide both sides by 4: y = 2x + 7
Slope is amount of change in y each time you change the x value one. In this case y=8x+7 the slope is 8 and the y intercept is when x is 0. In the case the y intercept is 7.
There is not a way to give the answer to this equation. You will have to give me the value of the letters.
