When 12x + 4y = 32 is written in y = mx + c form, what are the slope and y-intercept?

Answer and explanation

Correct answer: Slope -3, y-intercept 8

The governing concept is the slope-intercept form of a linear equation, y = mx + c. Here m is the slope and c is the y-intercept. Start with 12x + 4y = 32. Subtracting 12x from both sides gives 4y = -12x + 32. Dividing every term by 4 gives y = -3x + 8. Comparing the result with y = mx + c shows that m = -3 and c = 8, so option A is correct. Option B loses the negative sign when 12x is transferred to the other side. Options C and D incorrectly treat the original coefficients as the slope and intercept without first isolating y.
