Answer:
x*$10 + y*$16 = $480
Step-by-step explanation:
The question seems incomplete, and after a search online I've found a lot of similar questions with similar numbers, so I really can not be sure of which one is the complete question.
I suppose that we want to get a linear equation that describes the given situation:
Let's define two variables:
x = number of hours that Maggie works in the office (for $10 each)
y = number of hours that Maggie works driving a tractor (for $16 each).
Then the total amount of money that Maggie gets is:
x*$10 + y*$16
Now we know that she earns $480 per week, then we know that:
x*$10 + y*$16 = $480
This is a linear equation we wanted to get, where (just to be complete) we need to add the restrictions:
x ≥ 0
y ≥ 0
(this means that she can not work a negative number of hours).

Answer:
y = -4x + 2
Step-by-step explanation:
- We know that the equation of slope is y = mx + b
- We also know that the slope is -4 given in this problem
- So:
- y = -4x + b
- Using the point (-1, 6), we can substitute this point into the above equation to solve for b.
- (6) = -4(-1) + b
- 6 = 4 + b
- b = 2
- Therefore the equation of the line is y = -4x + 2
