Slope intercept form of the line that passes through (-1,3) and (-2,-3)

Answer

Step by Step

If you need to do it without graphing you subtract the coordinates. One and coordinate minus the other and the same x coordinate minus the other. You can switch around the order of the pairs but not individual coordinates.

1 - (-2) = 1

3-3=0

You then put whatever you get from the Ys over the x.

0/-1

In this case, the slope is 0/-1 which is zero. This means the line is horizontalal
