The y intercept in the scatter plot means that at 0 years working, you will get paid $8 per hr. The y intercept can be represented by the ordered pair (0,8). The independent variable is the # of years and the dependent variable is pay per hour.
Hope this helped :)

Okay the first one is : -2x^4/3y^3
and the second one is : y^7/x^4
the “^” are because i cant put them up so they’re exponents !
You can solve this type of question two ways:
First cross multiply:
<u>x </u> = <span><u>3</u>
</span>42 7
(42)(3) = (7)(x)
This becomes :
126 = 7x
To solve for x divide both sides by 7 and you get x = 18
The other way to solve it is to think, what do I need to do to get x all by itself?
Since it's being divided by 42, you need to multiply each side of the equation by 42.
42 * <u>x</u> = <span><u>3</u> * 42
</span> 42 7
This leaves you with x = (42*3)/2
This simplifies to x = 18
Answer:
X= - 44
18x+3x+4-5=5(4x9
Collect like terms
21x+4-5=5(4x-9
More variable to the left hand side and change its sign
21x-20x-1=-45
Correct like terms
X=-45+1
Which is x=-44
