Answer:
The slope is -3.75 or -15/4.
Step-by-step explanation:
The formula for slope is the change in y over the change in x.
To do this, you subtract 7-3 to get you 4 on the bottom of the fraction and -7-8 which is -15.
So pretty much, you get -15/4. :)
-12+3b-1=-5-b
Combine like terms to get:
3b-13=-5-b
Add 13 to both sides:
3b= 8-b
Add b to both sides:
4b=8
Divide both sides by 4:
4b/4=8/4
b=2
Final answer
b=2
