which equation best represents line m?

Answer:
The equation that best represents line m is y = 3x - 4.
Step-by-step explanation:
Line m is a black line that slants upwards from left to right.
The slope of the line is 3, because for every 3 positions you move up You must also move 1 position to the right.
The y-intercept of the line is -4, because the line crosses the y-axis at -4.
Putting all of this together, the equation that best represents line m is y = 3x - 4.
