Compare the slopes of the 4 equations, which is the number in the term with "x". The slope with highest absolute value is the steepest. Positive slope means the function is ascending left to right, negative slope means it is descending left to right. If you only care that it is the steepest, regardless of whether it is ascending or descending, then the answer is (D).
The correct answer is A.
Here is the completed problem:
3(4x+5)=12
Distributive property.
3(4x+5)=12
Simplify
12x+15=12
Subtract 15 from both sides.
12x+15−15=12−15
12x=−3
Divide both sides by 12.
12x/12 = −3/12
x= −1/4
