Answer:
D
Step-by-step explanation:
Stan works for 28 hours and gets paid $12 for each hour, so the amount of money he gets in total is $12*28 = $336.
Y=x-4
x=y+4
y=-3(y+4)
y=-3y-12
4y=-12
y=-3
x=1
Answer:
y=1/2x+2
Step-by-step explanation:
The equations come in the form of y=mx+c, where m is the gradient and c is the y-intercept. Looking at the graph we know that the y-intercept is (0,2), so that rules out options B and C.
To find the gradient is a little more tricky, but we can follow the formula:
, where rise is the vertical value and run is the horizontal value
So we sub in our values:

And simplify:

So now we sub in our new found values into y=mx+c:
y=1/2x+2
Not really sure what you mean by compare. The only thing I can think of is the y intercept is generally a good point to start from to count the rise/run
