Question

What is the y-intercept of the line given by the equation below?
y = 9/2x + 5
A. (0, -5)
B. (0, 9/2)
C. (0, 5)
D. (0, -9/2)

Answer 1

to get `y` intercept, plug in `x=0` in the equation

Answer 2

what you get when you put x=0 in
y = (9/2)x+5
?

Answer 3

5?

Answer 4

correct!
so the y intercept is
`(0,5)`
:)

Answer 5

does that go for every equation? like always put zero in where the x is to get my answer?

Answer 6

to get `y` intercept, plug in `x=0` in the equation
to get `x` intercept, plug in `y=0` in the equation
and yes :)

Answer 7

Ok just to make sure im doing this right before i close this question, the next question on the test was the same thing but the equation was different. y = -10x + 14
to find the answer put zero in for x and the answer would come out to be 14 right?

Answer 8

\(\Large y-intercept \equiv (0,14)\)
yes :)

Answer 9

Ok sweet thanks for the help! I'm sure i'll post another question if i dont get it.

Answer 10
