Answer:
slope: -11/7
Step-by-step explanation:
Slope is equal to the change in yy over the change in xx, or rise over run.
m=change in ychange in xm=change in ychange in x
The change in xx is equal to the difference in x-coordinates (also called run), and the change in yy is equal to the difference in y-coordinates (also called rise).
m=y2−y1x2−x1m=y2-y1x2-x1
Substitute in the values of xx and yy into the equation to find the slope.
m=19−(8)−9−(−2)m=19-(8)-9-(-2)
Simplify.
m=−11/7
