Question

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.

Answer 1

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
