2x+y = 10 or y = -2x + 10 so the slope is -2

2x+x-5 = 10 2x+x = 10+5 3x = 15 x = 5 and y = 0

y = 2x+10 Just change the y intercept.

y = 4x-8 and y = 2x+10 4x-8 = 2x+10 4x-2x = 10+8 2x = 18 x = 9 Substitute the value of x into the original equations to find the value of y: Therefore: x = 9 and y = 28

x + y = 10 y = x + 8 so, x + (x + 8) = 10 2x + 8 = 10 2x + 8 - 8 = 10 - 8 2x = 2 x = 1 and y = 9 because y = x + 8 y = 1 + 8 y = 9
