To convert the equation 8x - 5y = -40 into slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept, you need to solve for y. First, isolate y by subtracting 8x from both sides to get -5y = -8x - 40. Then, divide by -5 to get y = 8/5x + 8, which is the slope-intercept form of the equation. The slope is 8/5 and the y-intercept is 8.
8x+40
7. 8x-40=2x+2 4x-20=1x+1 3x-21=0 3x=21 therefore x=7
Let me assume that this equation is -2 -8x = 40 It's usually best to move all the purely numerical items to one side first. Let me move the -2. Then, to do this I add 2 to both sides. -2 - 8x +2 = -8x = 40 + 2 = 42 or -8x = 42 Now, to yield x 'by itself' let me divide both sides by -8. (-8x)/-8 = x = 42/(-8) = -21/4 or x = -21/4
