What is the slope of the line that contains these points? x| -7. -6. -5. -4 y| 21. 17. 13. 9

Step-by-step explanation:

Given the line containing the points.

x | -7. -6. -5. -4

y | 21. 17. 13. 9

The slope of the line is expressed as m = Δy/Δx = y₂-y₁/x₂-x₁

Using the coordinates y (21, 17) and corresponding value of  x(-7, -6)

y₁ = 21, y₂ = 17 x₁ = -7, x₂ = -6

Substituting the values into the formula for calculating the slope, we have;

m = Δy/Δx = 17-21/-6-(-7)

m = -4/-6+7

m = -4/1

m = -4

Hence the slope of the line that contains these points is -4

i would say c is the best answer, hope it's right!

good luck! =)

cutie~

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
