Use the slope equation:

Plug in the points (2, 15) and (0, -1).

⇒

= 8
The slope of the line is 8.
Answer:
d = 7.2
Step-by-step explanation:
We can cross multiply the equation to get:
6 * 30 = 25 * d
(* is multiplication sign by the way)
180 = 25d
Divide both sides by 25 to get:
d = 7.2
Can you tell how much she selled? Then I can answer it
your answer is 30
1^2 (raised to the power of 2) +2 is 3
5^2 +2 is 27
5^2=25
1^2=1
add 27+3=30
Y=3x
x-2
The correct answer is y=6
