Answer:
Equation of a line has form of y = ax + b
This line passes (-8, 8) and (1, 10), then:
-8 = -8 x a + b
10 = a + b
Subtract 2nd equation to 1st equation, then:
18 = 9 x a
=> a = 2
=> b = 10 - 2 = 8
=> y = 2x + 8
Hope this helps!

b = 40
Step-by-step explanation:
1/2 mile / 1/5 hour = x miles/ 1 hour
using cross products
1/2 * 1 = x * 1/5
multiply by 5 on each side
1/2*5 = x
x = 5/2 miles
x = 2 1/2 miles
The choose A.
I hope I helped you^_^
