Question

Write the following inequality in slope-intercept form.
12x − 3y ≤ −21

A.) y ≥ 4x + 7

B.) y ≤ 4x + 7

C.) y ≥ 4x − 7

D.) y ≤ 4x − 7

Answer 1

Answer:

A

Step-by-step explanation:

y≥ 4x+7

Answer 2

$12x -3y \leq -21\\\\\implies 12x +21 -3y \leq 0\\\\\implies 12x +21 \leq 3y\\\\\implies 3(4x +7) \leq 3y\\\\\implies 4x+7 \leq y\\\\\implies y \geq 4x+7$
