The points (3, 9) and (–3, –9) are plotted on the coordinate plane using the equation y = a • x. What is the value of a? Enter your answer in the box.

So fill out the coordinate with those given numbers, and count how far apart they are and you will get your answer. Then times it by x.

A = 3
because if we input x and y in y = a • x, then we get 9 = a • 3, and when you do the math, a will equal 3, same goes for (-3, -9) if you input them correctly on the equation

I’m pretty sure the answer is a
