Final answer:
The correct conversion of the equation (y+7)= 3(4x-8) to slope-intercept form is y = 12x - 31, which corresponds to option C.
Step-by-step explanation:
To convert the equation (y+7)= 3(4x-8) to slope-intercept form, we first need to distribute the 3 across the terms inside the parenthesis and then isolate y on one side of the equation.
First, distribute the 3:
3 × 4x = 12x
3 × -8 = -24
Now, our equation is:
y + 7 = 12x - 24
Next, we subtract 7 from both sides to solve for y:
y = 12x - 24 - 7
y = 12x - 31
Thus, the equation in slope-intercept form is y = 12x - 31.
Answer: C) y=12x-31
