So, I undestood slope right. But, I get confused with the other points that intersect there is multiple of them. How do i look f
ivanzaharov [21]

Answer:

slope = 2

Step-by-step explanation:

Find 2 points on the line that land perfectly on the grid. I'll choose these 2 here:

(-2, -1) and (0, 3)

Rise is the change in the y value from one point to the other, and run is the change in the x. Looking at these 2 points, y went from -1 to 3. That is a <em>rise</em> of 4. The x went from -2 to 0, so that is a <em>run</em> of 2. "rise over run" means rise literally over run in a fraction like this:

m=\frac{rise}{run}

The more proper way to calculate slope looks like this, but it's really the same thing in the end:

m=\frac{y2-y1}{x2-x1}

where (x1, y1) and (x2, y2) are your 2 points.

Finally, the slope of this line is:

m=\frac{3--1}{0--2}\\\\m=\frac{4}{2}\\\\m=2

That's a rise of 4 over a run of 2, and that simplifies to just a slope of 2.
