The equation of that line is [ <em>y = -3/4 x - 2</em> ].
The first number is x
the second number is 2x-4
combine both numbers = 80
x+2x-4=80
3x-4=80
3x=84
x=28
one number is 28 and the other is 52.
The equation that represents that line is
y=2/3x+5.
First, you have to find the slope (the change of y over the change of x which here is 2/3. Then, you put one of the points in and solve. I used (3,7) When you input them into the equation, you get 7=2/3 (3)+_ Which gives you 7=2+_ .
5+2 is seven, so the blank is 5. So, when you do that, you get Y=2/3x+5.
If you need more of an explanation, comment.
1 hr = 9.75
351/9.75= 36 hours
to check multiply 36X 9.75 = 351
27 i believe
you would substitute y with 0 to find x then you would put 9 in for x to find y then you would go back to the first equation and put -19 in for y and then solve for x and get 27
