Option (C) It means the technician charges a fixed amount of $75 for the repair is correct.
<h3>What is a straight line?</h3>A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
The graph of the equation is given:
From the graph the equation of the straight line will be:
y = 45x + 75
For the y-intercept plug x = 0
y = $75
The y-intercept represents the technician charging a fixed amount of $75 for the repair.
Thus, option (C) It means the technician charges a fixed amount of $75 for the repair is correct.
The graph is attached is in the picture.

The distance between two points (2,-2) and (0,-9) is 7.3 units, which is obtained by graphical method and formula method.
Step-by-step explanation:
The given is,
Two points are (2,-2) and (0,-9)
Step:1
By graphical method,
For two points (2,-2) and (0,-9)
First point (2,-2)
The values of x=2 and y=-9 noted in the graph
Second point (0,-9)
The values of x=0 and y=-9 noted in the graph
Now join the two points, measure the distance between the two points,
Distance between points are 7.3 units.
( OR )
Step:1
By formula method,
Distance =
Where,
( 2,-2) are ()
(0,-9) are ()
From the values,
=
=
=
=
= 7.280
≅ 7.3
Distance = 7.3
Result:
The distance between two points (2,-2) and (0,-9) is 7.3 units, which is obtained by graphical method and formula method.
