Use the equation to find the slope: m=y2-y1/x2-x1 and plug in each of the y coordinates into the numerator and each of the x coordinates in the denominator
m=-2-3/4-8
-5/-4
m=5/4
Plug in the slope and one of the ordered pairs into y=mx+b. I’ll use (8,3)
3=5/4(8)+b
3=10+b
-7=b
Equation: y=5/4x-7
-sqrt(y) = -5
Multiply
each side by (-) negative sign: sqrt(y) = 5
Square each
side: y = 25
Answer: (C) 25
The unit rate is a ratio of change in y and into the change on x. It can also be the rise to run or the slope.
