Answer:

-25

Step-by-step explanation:

You must first pick two points. I picked the points of (4, 400) and (8, 300). You can pick different points and still get the right answer.

Subtract the y's and the x's. Divide the difference of y by the difference of x.

400 - 300 = 100

4 - 8 = -4

100/-4 = -25

The slope, or rate of change, is -25.

Robert is a high school basketball player. In a particular game, he made some three point shots and some free throws (worth one

Oksanka [162]

Answer:

let t = number of three-point shots

let f = number of free throw shots

Step-by-step explanation:

t + f = 9 (he made a total of 9 shots altogether)

3t + 1f = 23 (number of shots multiplied by their point value)

substitution method: t = 9 - f

3(9 - f) + f = 23

27 - 3f + f = 23

-2f = -4

f = 2

find 't': t + 2 = 9

t = 7
