To find the slope, use the simple rule rise/run. The change in the y value over the change in the x value. The y changes by -1 when the x changes by positive 2. Therefore, the slope is -1/2.
Use the slope formula.
Y2 - Y1 / X2 - X1
(-7 - 5) / (9 - -2)
(-12) / (11)
So answer: slope(m) = -12/11
Answer:

Step-by-step explanation:
You really just have to do 12.4 x 2 = 24.8 because half of 24.8 is 12.4.
