First of all, the y-intercept of this line is -5, which means our line crosses the y-axis at (0, -5)
Remember, a y-intercept always has an x-coordinate of 0.
So, we plot a point at (0, -5)
Now, the slope is 2. Which means that we plot the next point after going up 2, over 1. Then, we plot the next point, and so on..
When we are done, the line should look like so:
