Answer:


-(2)/(25)

Step-by-step explanation:

Slope is rise over run.


m=(rise)/(run)=(y_2-y_1)/(x_2-x_1)

We are given the points (–20, 18) and (30, 14).


m=(14-18)/(30+20)=(-4)/(50)=-(4)/(50)=-(4/2)/(5/2)=\boxed{-(2)/(25)}

The slope is -2/25.

Answer: the fraction -2/25

Step-by-step explanation:

Use the slope formula. We subtract the y values together, and do the same for the x values as well. Subtract in the same order each time. Then you divide the two results. Reduce the fraction if possible.

m = (y2 - y1)/(x2 - x1)

m = (14 - 18)/(30 - (-20))

m = (14 - 18)/(30 + 20)

m = -4/50

m = -2/25
