7 and -6
or
-7 and 6
m(slope)= change in y/change in x
m=-17-(-5)/3-1
m=17+5/2
m=22/2
m=11
Answer: B
Step-by-step explanation:
To isolate x, you divide both sides by 21
21x=7

x = 7/21
Simplify by dividing both the numerator and denominator by 7
x = 1/3
Since, 1/3 is not an option, B is the correct answer
As decimals lets look at them:)
7/8 = 0.875
3/4 = 0.75
In this case 7/8 is actually bigger.
