Question

What is the slope and y- intercept of y = 4

Answer 1

help

Answer 2

You are asking where this line intercepts the y-axis. What does the graph of y = 4 look like? Do you know? I can help you if not.

Answer 3

i don't know they just gave me that equation and told me to find the y intercept and the slope. all of the other equations looked like y = 3x - 9 but this one and another one is different.

Answer 5

Right... this equation is actually a straight line. For any value of x, the corresponding y value is always 4. So, x = 3 then y = 4... or x = 1.235 then y = 4. So, if x = 0 then y = ?

Answer 6

4?

Answer 7

exactly! Which is the same thing as the y intercept. Good job.

Answer 8

so what would the slope be. 0?

Answer 9

The slope would be rise over run.

So, for any run... the rise is 0 therefore the slope is 0. So, yes.

Answer 10

thanks could you help me with one more

Answer 11

@luffingsails ????

Answer 12

Sure. go ahead.

Answer 13

Sorry, my connection isn't the best from work. I'm still here.

Answer 14

what is the y intercept and slope of y = -x

Answer 15

Remember to find the y intercept... just let x = 0 and solve for y. So, what is it for this problem when you let x = 0?

Answer 16

0??

Answer 17

Yes, exactly. That is the y-intercept.

Answer 18

The slope is the coefficient of the x term.

remember the form is y = m * x + b... where m is the slope and b is the y-intercept.
You have y = -x or y = (-1) * x + 0.

so, m = -1... and b (your y-intercept) = 0.

Answer 19

and the slope is 0?

Answer 20

so the slope is 1?

Answer 21

Slope is -1 the negative sign is important here.

Answer 22

ok thank you

Answer 23

sure.
