• Coordinates (x, y)
• Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (-9, 9)

Point (3, 9)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

1. Substitute in points [Slope Formula]:                                                            $\displaystyle m=\frac{9-9}{3+9}$
2. [Fraction] Subtract/Add:                                                                                    $\displaystyle m=\frac{0}{12}$
3. [Fraction] Divide:                                                                                               $\displaystyle m=0$

Answer 2

Answer:

This question has a slope of zero.

Step-by-step explanation:

When trying to solve a problem like this, what I recommend doing is subtracting the y value in the first ordered pair from the y value in the second ordered pair, and doing the same for the x values. To write it as a formula,

y2 - y1

––––– = m          the 2 in the formula means that the y or x value was from the  

x2 - x1                  second ordered pair. The 1 means it was from the first                                      

                            ordered pair. The m means slope.
