Step-by-step explanation:
<u>According to the graph, the line has the following intercepts.</u>
- y - intercept of (0, - 3)
- x - intercept of (6, 0)
<u>The line equation is:</u>
<u>The slope is:</u>
- m = (0 - (-3)) / (6 - 0) = 3/6 = 1/2
<u>The line is:</u>
Answer:
I believe that it is a line, since a line is infinite

Answer:
Both sports = 15
Step-by-step explanation:
Remark
What an interesting question. At first I didn't think it was possible. Then I saw the word only. That made all the difference in the world.
Givens
Football only = 35
Volleyball only = 15
Ratio = 5/3
Equation
Let the number of students who play both = x
Volleyball / Football = (x + 15) /(x + 35) = 3/5
Solution
(x + 15) / (x + 35) = 3/5 Cross multiply
5*(x + 15) = 3(x + 35) Remove the brackets
5x + 75 = 3x + 105 Subtract 3x from both sides
<u>3x 3x</u>
2x + 75 = 105 Subtract 75 from both sides
<u> - 75 -75 </u>
2x = 30 Divide by 2
2x/2 = 30/2
x = 15
15 people play both sports.
