Question

I don't jus want the answer, I want the walk through too.
Select the correct slope and y-intercept for the following equation. x-y=3x-7
A.) Slope m=-2, y-intercept b=7
B.)Slope m=2, y-intercept b=-7
C.) Slope m=-2, y-intercept b=-7
D.) Slope m=3, y-intercept b=-7

Answer 1

HI!!

Answer 2

is it
\[x-y=3x-7\]?

Answer 3

yes

Answer 4

if you want the slope and the y intercept, you have to make it look like
\[y=mx+b\]
that means you need to solve for \(y\)

Answer 5

this should take only two steps
1) subtract \(x\) from both sides
2) change all the signs (multiply by \(-1)\)

Answer 6

let me know what you get, or if it is still not too clear

Answer 7

Why multiply by -1?

Answer 8

because when you subtract \(x\) from both sides, you will have \(-y\) on the left, and you want \(y\) not \(-y\)

Answer 9

ohhhh ok

Answer 10

okay that makes sense now xD thanks!
