Question

Which equation represents the same proportional relationship as the graph?

On a coordinate plane, a line goes through points (0, 0), (5, 3), (10, 6).
y = three-fifths x
y = five-thirds x
x y = three-fifths
x y = five-thirds

Answer 1

y = (3/5)x

Explanation: slope = (change in y)/(change in x) = (3−0)/(5−0) = 3/5, and the line passes through the origin so y = (3/5)x.
