Given the equation 8x = 4y + 16, generate a plan to rewrite it in slope-intercept form. Which variable do you solve for?

Answer:

To rewrite the equation 8x = 4y + 16 in slope-intercept form (y = mx + b), I need to solve for the variable y. First, I would subtract 16 from both sides of the equation to isolate the term with y, which gives 8x - 16 = 4y. Then, I would divide both sides by 4 to get y by itself, resulting in y = 2x - 4.
