Question
Change the equation from standard form to slope-intercept form by solving for y.
11x - 8y = -48
Bob:
Subtract 11x from both sides: -8y = -59x
Divide by -8 on both sides: y = 7.375
Bill:
Subtract 11x from both sides: -8y = -11x - 48
Divide by -8 on both sides: y = 11/8 x + 6
Bud:
Subtract 11x from both sides: -8y = -11x - 48
Divide by -8 on both sides: y = -11x + 6

To solve for y in slope-intercept form, the equation should be rearranged to y = mx + b, where m is the slope and b is the y-intercept.
Bob's answer of y = 7.375 is not correct as it does not have an x term. Bill and Bud both made an error in their calculation. The correct answer should be:
11x - 8y = -48
-8y = -11x - 48
y = (11/8)x + 6
Therefore, none of them provided the correct answer.
