Choose number 2, it is divisible by 2,
but it is not divisible by 4, because
but
.
The answer should be (8, -7)
Solve for
x
x
by simplifying both sides of the equation, then isolating the variable.
x
=
−3
Answer:
C=$0.33L-$43.76
I hope this is good enough:
The first thing to do with these problems is to convert them into y=mx+b form; this will literally show you the answer to slope and y intercept since m=slope and b=y intercept.
To convert, isolate the y and the rest should fall into place. Subtract 2x from 4y and the other side of the equation to get the equation 4y= -2x+9 (put the x first because of mx+b). Then Divide the 4 from y and do the same to the other side to get y= -1/2x+9/4. M= -1/2 so that is the slope. B=9/4 so that is the y intercept
