Interesting Question
What you are being asked is What is the line Perpendicular to AB going through point (7,6)
Step One
What is the slope of the given line
-7x + 3y = -21.5 Add 7x to both sides.
3y = 7x - 21.5 Divide by 3
y = 7x/3 - 21.5/3
The slope of the given line is 7/3 (just read it)
Step Two
What is the slope of the line perpendicular to it.
The slopes are connect by the formula
m1 * m2 = - 1
m1 = 7/3
7/3 * m2 = - 1 Multiply by 3/7
m2 = - 1 * 3/7
m2 = - 3/7
Step three
Find the y intercept, where b in the equation below is the y intercept..
y = -3/7 x + b
y = 6
x = 7
6 = -3/7 * 7 + b
6 = -3 + b Add 3 to both sides.
6 + 3 = b
b = 9
Step Three
State the equation
y = - 3/7 x + 9
Now you have to juggle the numbers to get the answer.
Step 4
put the -3/7 x on the left side.
y + 3/7 x = 9 Multiply both sides by 7
7y + 3x = 63 Now for some strange reason, you divide by 2
3.5y + 1.5x = 31.5 The answer is the second one down (middle one).

Did u make this???????????
Step-by-step explanation:
But i would say
C infinite cuz it could be
To find the number of chaperones, you could find the total number of students that are going on the field trip and then break this number into groups of 8.
(158 + 139)/8
297/8 = 37.125
You will need a minimum of 38 chaperones for the 297 students. If there is any remainder(decimal) you will need an extra chaperone so the groups do not exceed 8.
If the graph is out of 100 people that means one person is one percent. So 22% of adults like basketball and 15% like baseball, add the two together and you get 37 percent
