(5,22.45),(7,25.45)
slope = (25.45 - 22.45) / (7 - 5) = 3/2 or 1.5
y = mx + b
slope(m) = 1.5
use either of ur points...(5,22.45)...x = 5 and y = 22.45
now sub and find b
22.45 = 1.5(5) + b
22.45 = 7.5 + b
22.45 - 7.5 = b
14.95 = b
so ur equation is : y = 1.5x + 14.95.......this means that each quart of oil costs $ 1.50 and the labor fee costs $ 14.95

Step-by-step explanation:
Sum
-2d + 1 + 6d + 4
Solving like terms
4d + 5
Difference
-2d + 1 - 6d - 4
-8d - 3
Answer:
- 1/2
Step-by-step explanation:
We use the slope-intercept form to figure out our slope.
y = mx + b
Get y alone:
x + 2y = -8
2y = -x - 8
y = -x/2 - 4
Since m is the slope in y = mx + b, we can see that -1/2 is in the place of m, therefore our slope is -1/2

Hello! :3
Answer:
The Correct Answer is <u><em>365 °F</em></u>
Step-by-step explanation:
The C to F formula is
When we do 185 for C in the formula, we get
To solve, we first multiply 9 by 185, then we divide the product by 5, and then finally we add 32 to the quotient to get the answer.
Therefore, the answer to 185 C to F is 365 which can be written like this
⇒ 185 °C = 365 °F
hope this helps you!
Have an Awesome Thursday!
