For this case we have that by definition, the equation of a line in the slope-intersection form is given by:
Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis
We have the following points:
Substituting we have:
Thus, the equation is of the form:
We substitute one of the points and find "b":
Finally, the equation is of the form:
Answer:
Use the property that angles sum up to 360 degrees.
Also use property that <M = <R and <A = <P.
That gives the following equation:
m<R + m<A + m<M + m<P = 360
6x+5 + 9x+25 + 6x+5 + 9x+25 = 360
30x + 60 = 360
x = 10
Answer:
x = 10
m<M = 6x+5 = 65 degrees
(20+2.5)x = cost
when x equals number of tickets
(20+2.5)24 = 540
Hope this helps :D

She did 12 questions, and needs to do 36.
36 / 12 = 3, so it will take 3 times as long.
1 hour 20 minutes times 3 = 4 hours.
It will take her 4 hours.
