What are the given side lengths?
If we place 0 and 1 for the x then:

this is the line:
I recommend you use google because these are very easy
Answer:b= -0.5
Step-by-step explanation:
>-3b+2.5=4
>-3b=1.5(subtract 2.5 from both sides)
>b=-0.5 (divide both sides by -3)
The x intercept is not 10!
f(x)=0.75x-7
x= 7/0.75 ≠ 10
so last one is false!
(for finding x intercept make the y/f(x) value 0)
