WebStep 4: Plug in -4 (representing the space in between the points -3 and -5 on the number line) into the (x+3) (x+5) and solve. (-4+3) (-4+5)= -1 The answer is negative. Step 5: Look at x^2+8x+15<0. The answer is suppose to be LESS than 0, which means that the answer has to be a NEGATIVE number.

Graphing a line given point and slope (video) Khan Academy
WebTo do that, we take the y value of our first point (our first point is (5, 6) so the y value is 6): 6. And subtract the y value of the other point (the other point is (3,2) so the y value is 2): 6-2=4. So our change in y or rise is 4. Now we can finish by putting the rise over run :D. Rise = 4. Run = 2. Slope = 4/2.
