<u>We know that:</u>
Slope of a line = change in y coordinate / change in x coordinate
<u>We are given:</u>
First point = (2,5)
Second point = (5, 14)
<u>Calculating the change in y coordinate:</u>
change in y (also represented by Δy) = second y - first y
Δy = 14 - 5
Δy = 9
<u>Calculating the change in x coordinate:</u>
Δx = second x - first x
Δx = 5 - 2
Δx = 3
<u>Slope of the line:</u>
Slope = (Δy) / (Δx)
Slope = 9 / 3 [replacing the values]
Slope = 3
<u>old:</u> $16
<u>new:</u> $20
<u>percent increase</u>
-> formula: (new-old / old) x 100
(20-16 / 16) x 100
4/16 x 100
0.25 x 100
answer: 25% increase

9.75 is the FINAL answer
Answer:
volume = 504
Step-by-step explanation:
the basic formula for volume is length × width
14 x 3 x 3 x 2 x 2 = 504
Answer:
x = -3/2
Step-by-step explanation:
4(x + 3) = 6
4x + 12 = 6
4x = 6 - 12
4x = -6
x = -6/4
x = -3/2
