Question

Could someone please check if I'm right on this question?
⦁ Model the function rule y = -2x - 3 with a table of values. Show your work.
My answer: y=-2x-3
y=-2(0)-3
y=0-3
y=-3
x=0 y=-3
I went on plugging the x with 1,2,3,4 and 5..
Am i correct or not?

Answer 1

correct

Answer 2

yes, when x = 0, y = -3. This call also be written as (0, -3).

It's in the form of (x, y).

What y-values did you get when you plugged in x = 1, 2, 3, 4, 5?

Answer 3

They asked me another question with it that confused me they asked ⦁ For the function rule y = -2x - 3, provide the x-y coordinates of the y-intercept and the x-intercept. Show your work.

Answer 4

ohhhh they were, -5,-7,-9,-11, and -13

Answer 5

those values are correct

to find the x-intercept, you plug in y = 0 and solve for x
to find the y-intercept, you plug in x = 0 and solve for y

Answer 6

plug in 0 for all of them?

Answer 7

only y=0 for x-intercept, and x=0 for y-intercept

Answer 8

to find the `x-intercept`, you plug in `y = 0` and solve for `x`
to find the `y-intercept`, you plug in `x = 0` and solve for `y`

Answer 9

I'm still a little confused on that sorry ):

Answer 10

X intercept is when the function hits the x axis, which then the y is zero, and vise versa.
