HURRY I’LL MARK BRAINLIEST!! A carpenter charges a callout fee of $135 plus S45 per hour.
Write an equation to represent the total amount charged y by the carpenter as a function of the number of hours worked r.

y=45r+135

Step-by-step explanation:

so 45 dollars is the money earned per hour (r)

and we add 135 because they charge 135 dollars for the callout fee

hope this helps!

y=135+45r

Step-by-step explanation:

You start with a fee of 135 and then you add the 45 times the hours, that's how you get the total amount.

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
