Using your approximate y-intercept on the line of best fit, your equation would be y=11/7x + 3. 

We find the slope by choosing two points that are on the line:

(9, 18) is easy to spot; and (2, 7) is fairly easy to spot as well.  The formula for slope is:
m=y₂-y₁/x₂-x₁

m=7-18/2-9 = -11/-7 = 11/7

Slope intercept form, y=mx+b, has the slope and the y-intercept.  Plugging those in we have y=11/7x+3.

The generic equation of the line is:
 y-yo = m (x-xo)
 We look for the slope:
 m = (y2-y1) / (x2-x1)
 m = (18-15) / (9-7)
 m = (3) / (2)
 m = 3/2
 We write the equation choosing any point:
 y-15 = (3/2) (x-7)
 we rewrite the equation:
 y-15 = (3/2) x-10.5
 y = (3/2) x-10.5 + 15
 y = (3/2) x + 4.5
 Then, for x = 13 we have:
 y = (3/2) * (13) +4.5
 y = 24
 Answer: 
 The equation is:
 y = (3/2) x + 4.5
 
The number of matches won for 13 months is:
 y = 24

Tyrell wants to buy a pair of shoes with an original price of $75. He has a coupon for 25% off. What is the price of the shoes o
kirza4 [7]
$56.25, since 25% off can also be written as ÷4, since 25 is a quarter. 75÷4=18.75
75-18.75=56.25.               Therefore, the answer is $56.25

Find the solution to the given equation if the replacement set is {6, 9,15,16}.
Alexxandr [17]
They gave you a set of numbers that you replace the variable x in the equation to see if it gives a correct answer so just do exactly that.

6 + 2x = 24
6 + 2(6) = 24
6 + 12 = 24
18 = 24      so incorrect. both sides are not equal to each other.

6 + 2x = 24
6 + 2(9) = 24
6 + 18 = 24
24 = 24       so correct. both sides are equal to each other.

6 + 2x = 24
6 + 2(15) = 24
6 + 30 = 24
36 = 24       so incorrect. both sides are not equal to each other.

6 + 2x = 24
6 + 2(16) = 24
6 + 32 = 24
38 = 24      so incorrect. both sides are not equal to each other.

so your answer is b) 9

hope this helps, God bless!

The surface area stays the same, but the number representing the surface area decreases.

Does that answer the question, or am I wrong?
