Answer:
8
Step-by-step explanation:
f (x) = 7 (x-1) +8
For f(1) we plug 1 into x.
f(1) = 7 (1-1) +8
Simplify
f(1) = 8
I think it's along the y-axis.....
The fromula of a slope:
We have the points 
and 
Substitute:
<h3>Answer: slope is undefined.</h3><h3 />
It's a vertical line: 
Answer: " b = 3 ⅕ ; or, write as: 3.2 .
_____________________________________
Given: "A = (1/2) * b * h " ;
↔ A = (b * h) / 2
2A = (b*h) ;
2A/ h = b ;
↔ b = (2A) / h ;
Given A = 48 ; and h = 30 ; Plug in these values; and solve for "b" ;
→ b = (2*48) / 30 ;
= 96/30 ;
= (96÷6) / (30÷6) ;
→ b = 16/5 ; = 3 <span>⅕ ; or, write as: 3.2 .
