The equation y = 30x + 40 represents the line of best fit showing ted’s earnings in terms of the number of hours he works as a plumber. if x is the number of hours he works and y is ted’s earnings, which statement describes this situation correctly? ted’s initial charge is $30, and his hourly charge is $40. ted’s initial charge is $40, and his hourly charge is $30. ted does not charge an initial amount, and his hourly charge is $40. ted does not charge an initial amount, and his hourly charge is $70.

 Ted’s initial charge is $40, and his hourly charge is $30.

Step-by-step explanation:

We know that the general equation of a line in intercept form is given by :-

, where m is the slope of the line and c represents the y-intercept of the function.

The given function :-The equation represents the line of best fit showing Ted’s earnings in terms of the number of hours he works as a plumber.

Here, Slope =30

The y-intercept = 40

If x is the number of hours he works and y is Ted’s earnings.

Then by comparing the general equation of line in intercept form,  the initial amount charged by Ted =y-intercept = $ 40

His hourly charge = Slope = $ 30

the answer to the question is a

step-by-step explanation:

it has the same slope and the same y-intercept.

y + 11 = -7/9(x - 18)

y + 11 =-7/9x + 14

b

y = -7/9x + 3

y-intercept (0, 3)

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
