Given:
A surf instructor has an initial fee of $12 and charges $8 per hour for lessons.
To find:
The y-intercept and its location on the graph.
Solution:
Initial fee = $12
Variable fee = $8 per hour.
Let the total fee be y for x hours. Then,
Put x=0, to find the y-intercept.
Therefore, the y-intercept is 12.
Table of values for ,
x y
0 12
-1 4
Plot (0,12) and (-1,4) on a coordinate plane and connect them by a straight line.
Clearly, the y-intercept is located at (0,12).
y=5x-8
5x=y+8
x=y/5+8/5 is the inverse of f(x)
Answer: -3/2
Step-by-step explanation:
There are two methods to find the slope
METHOD 1. Rise/Run
Rise: the y-axis value
Run: the x-axis value
In the graph, rise/run=3/2
The line is going down, so it should be negative
-3/2
Hope this helps!! :)

Answer:
72/97
Step-by-step explanation:
take angle c as reference angle
to find sin c
sin c = opposite / hypotenuse
sin c = 72 / 97
Answer:
x = 1
Step-by-step explanation:
Add 4 from both sides which you add to the zero. Then, combine like terms, 5x - 1x which is 4x. Divide 4 from both sides and it equals 1.
