With the information provided, we can begin with the equation:
y=35x + b
With x = number of hours, y = total cost, b = fixed amount that is charged for residential work
We know that after 6 hours, $270 was charged:
$270 = $35(6) + b
Solve for b:
b = $270 - $210 = $60
The fixed amount that is charged for residential work is $60. So now we can rewrite the equation as:
y = 35x + 60
Answer:
3rd one
Step-by-step explanation:
Answer:
We conclude that the equation of the line is:
Step-by-step explanation:
The slope-intercept form of the line equation

where
Given the data table
x -3 -5 -7 -9 -11
y -16 -26 -36 -46 -56
From the table taking two points
Determining the slope between (-3, -16) and (-5, -26)




Thus, the slope of the line is: m = 5
substituting m = 5 and (-3, -16) in the slope-intercept form of the line equation to determine the y-intercept b

-16 = 5(-3) + b
-16 = -15 + b
b = -16+15
b = 1
Thus, the y-intercept b = 1
now substituting m = 5 and b = 1 in the slope-intercept form of the line equation


Therefore, we conclude that the equation of the line is:
