Question

The equation of a line is x + 5y = 12. What is the y-intercept of the line?

Option A: -12

Option B: 12

Option C: 5/12

Option D: 12/5

Answer 1

first you need to move isolate the y intercept onto one side

Answer 2

would it be 12?

Answer 3

put your equation in y = mx + b form, and the b position is the y intercept

Answer 4

go on mathway.com it could help :)

Answer 5

I think it's 12 but I'm not sure

Answer 6

no..its not 12

Answer 7

put your equation in y = mx + b form

x + 5y = 12 --- subtract x from both sides
5y = -x + 12 -- divide both sides by 5
y -x/5 + 12/5

now..in y = mx + b form, the y intercept is in the b position.

So what do you think the answer is now ?

Answer 8

oops...typo...y = -x/5 + 12/5

Answer 9

12/5?

Answer 10

D

Answer 11

you got it...12/5 is the y intercept.
And just to let you know, if you were looking for the slope, it is in the m position...it would be -1/5

Answer 12

oh yeaah, I get it now. Thank you sooooo much! :))

Answer 13

anytime :)
