    Answer:

    y = x

    Step-by-step explanation:

    So what we’re going to want to do here is use the slope formula and the general equation y = mx + b.

    Let’s start.

    The slope formula is y2-y1/x2-x1. So, put our points in here. 4-0/4-0. Slope: 1.

    Okay, we have that. Now, a line that passes through the origin (0,0) is not going to have a y-intercept because it hits the y-axis at 0. So, that cancels out the b.

    With our slope 1, the answer is just y = x. Very simple equation.

    Hope this helped!
