The slope of each line segment of ΔQRS are-
- QR = 3/10
- RS = - 10/3
- QS = -7/13
<h3>What is meant by the slope of the line?</h3>
- A slope of a line is defined in mathematics as the change in y coordinate to regard to the shift in x coordinate.
- The net change in y-coordinate is denoted by Δy, whereas the net change in x-coordinate is denoted by Δx.
For the given question,
The coordinates of each vertices of the triangle are-
Q = (-7, -2)
R = (3, 1)
S = (6, -9)
The formula for the slope of the line segment.
Slope = m = (y2 - y1)/(x2 - x1)
Slope QR = (1 + 2)/(3 + 7)
Slope QR = 3/10
Slope RS = (-9 - 1)/(6 - 3)
Slope RS = - 10/3
Slope QS = (-9 + 2)/(6 + 7)
Slope QS = -7/13
Thus, the slope of the each line segment of the given triangle QRS is found.

Answer:
d
Step-by-step explanation:
Answer:
A. $ 46
B. 12 people.
Step-by-step explanation:
From the question given above, we obtained the following:
C(x) = 6.5x + 20
Where:
C => total cost of bowling
x => number of people
A. Determination of the of bowling for 4 people.
Number of people (x) = 4
Total cost (C) of bowling =?
C(x) = 6.5x + 20
C(4) = 6.5(4) + 20
C(4) = 26 + 20
C(4) = $ 46
Thus, it will cost $ 46 for 4 people to bowl
B. Determination of the number of people that can bowl for $ 98.
Total cost (C) of bowling = $ 98
Number of people (x) =?
C(x) = 6.5x + 20
98 = 6.5x + 20
Collect like terms
98 – 20 = 6.5x
78 = 6.5x
Divide both side by 6.5
x = 78 / 6.5
x = 12
Thus, 12 people can bowl for $ 98.
