Problem
the equation y = ax describes the graph of a line. If the value of a is positive, the line:
Step-by-step solution
The equation $y = ax$ represents a line passing through the origin. The coefficient $a$ is the slope. If $a$ is positive, the slope is positive, meaning the line goes up as $x$ increases (to the right).
Answer
