Question

Is this right? make sure you know I am trying to get a 100 on this assignment!

Answer 1

Answer:

no

Step-by-step explanation:

a is 2/3 because to find slope it is change in y over change in x so it would be 1-5/1-7 which is -4/-6 which is equal to 2/3

b has a slope of 3/2 because to find slope it is change in y over change in x so it would be 1-7/1-5 which is -6/-4 which is equal to 3/2

c has a slope of 1  because to find slope it is change in y over change in x so it would be 5-2/2--1 (-1 changes to positive because the double negative makes a positive) which is 3/3 which is equal to 1

d has a slope of  1  because to find slope it is change in y over change in x so it would be 5--4/2--7 (-1 changes to positive because the double negative makes a positive) which is 9/9 which is equal to 1

Answer 2

Answer:

No

Step-by-step explanation:

I'll do a quick run-through using the slope equation to verify your answers:

Remember that the slope equation is $m=\frac{y2-y1}{x2-x1}$.

A. (1,1) and (7,5)

$m=\frac{5-1}{7-1}=\frac{4}{6}=\frac{2}{3}$

$m=\frac{2}{3}$

B. (1,1) and (5,7)

$m=\frac{7-1}{5-1}=\frac{6}{4}=\frac{3}{2}$

$m=\frac{3}{2}$

C. (2,5) and (-1,2)

$m=\frac{2-5}{-1-2}=\frac{-3}{-3}=1$

$m=1$

D. (2,5) and (-7,-4)

$m=\frac{-4-5}{-7-2}=\frac{-9}{-9}=1$

$m=1$

Check your work and make sure you're entering the points into the formula correctly. I hope this helps!
