Question

Write each equation in slope-interept form then identify the slope and y intercept for each line. 2x - y =12

Answer 1

whats the answer

Answer 2

This is the only information that I was given for the question
I don't know how to put in slope intercept form struggling with this

Answer 3

slope intercept from is "y=mx+b", where m= slope, and b = the y-intercept. You have to get y on it's own to have this equation in slope-intercept form.

Answer 4

so it would be y = 12 - 2x

Answer 5

Does anyone know if I got the equation correct y = 12-2x

Answer 6

show me the steps you used to get to that answer. by the way, the slope always comes before the intercept.

Answer 7

I subtracted 2x from both sides to y by itself

Answer 8

ok, once you do that is should be -y=2x-+12

Answer 9

and you cannot have a -y. it has to be positive.

Answer 10

you lost me

Answer 11

ok. your staring equation is "2x-y=12"
Then you subtracted 2x from both sides... : "-y=-2x+12"
But, you cannot have a -y, it has to be positive. so, divide everything by -1 so that y can be positive. That is the slope-intercept equation.

Answer 12

ok got it thank you

Answer 13

so. what do you get as your slope and y-intercept?

Answer 14

y = 2x/2 +12/2
y = x + 6
x + 6 = 2(x + 6) + 12
x +6 = 2x +24
6 = 2x/x +24
6 -24 =2x
-18/2 = 2x/2
x = 9

y = 2(9) + 12
y = 18 +12
y = 30

Answer 15

uh, no. you really over thought it. The slope is whatever is before x, and the y-intercept is the number after the slope. Example: with the equation "y=3x+5", the slope would be 3 (or 3/1, same thing), and the intercept would be 5.
