You can verify that on the equation. We moved 5 to the right. Let's use these two points to calculate the slope m of this line.

Our y-intercept. Provided by: OpenStax.

If I move 1 in the x-direction, I move up 2 in the y-direction. This point will always have an x coordinate of zero. It has two slider bars that can be manipulated. That's our end point. When we go over by 3, we're going to go down by 2.

So slope is negative 1. But you must use the same order for both the numerator and denominator!
