Landon found the slope of the line passing though (3, 8) and (-4,-2). -4-3 -2-8 -7 10 7 = 10

For slope, you need to use the equation y2-y1/x2-x1.

In this case, you would substitute the values so it should look like this: -2-8/-4-3. Judging by this, your slope will be -10/7.

I don’t know if this is what you were looking for but hope this helps!
