A. A Plus Plumbing company charges $60 per hour and $80 as a one-time fee cause 320-140/4-1 equals 180/3 equals 60 and y-140=60(x-1)
y=60x-60+140
y=60x+80
The equation of the line is y = -2x + 16 which passes through the point (4, 8) and has a slope of -2.
<h3>What is a linear equation?</h3>
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The line that passes through the point (4, 8) and has a slope of -2.
On comparing the standard equation:
y = mx + c
Here m is the slope of the line and c is the y-intercept.
m = -2
y = -2x + c
Plug x = 4 and y = 8
8 = -2(4) + c
c = 16
y = -2x + 16
Thus, the equation of the line is y = -2x + 16 which passes through the point (4, 8) and has a slope of -2.

Answer:
Step-by-step explanation:
the slope equation is (y2-y1)/(x2-x1)
Answer is C because it’s asking for the sum of h and 3 which is then divided by 6
