Answer: (y - 3) = 7/6 (x - 4)
Step-by-step explanation:
The formula for point slope form is (y-y₁) = m(x-x₁)
Parallel lines will always have the same slope, so the slope of the new line is still 7/6.
The line goes through point (4, 3),
so x₁ = 4, and y₁ = 3 as points are written as (x, y).
Answer:
(a) 12 hours
(b) $220
Step-by-step explanation:
(a) First we plug in $364 for C
C=76+24h
364=76+24h
Subtract 76 from both sides
24h=288
Divide both sides by 24
h=12
She spent 12 hours fixing the drain
(b) First we plug 6 hours in for h
C=76+24(6)
Multiply it out
C=76+144
Add
C=220
It costs $220 for fixing a drain that takes 6 hours

Answer:
-10 and 2
Step-by-step explanation:
1. Think about what numbers multiply to -20: -10 and 2, 10 and -2, -20 and 1, 20 and -1, 4 and -5, -4 and 5
2. Then, think about which of the above adds to -8. This leaves you with -10 and 2
