Question

For the function rule y = -2x - 3, provide the x-y coordinates of the y-intercept and the x-intercept.

Answer 1

Do you know what the intercepts are?

Answer 2

For the \(x\) intercept, you replace \(y \) with 0. \[0 = -2x - 3 \Longrightarrow 3 = -2x \Longrightarrow x = {-3 \over 2} \]

Answer 3

So, \[x = {-3 \over 2}, y = 0 \Longrightarrow (-1.5,0) \] that is the x intercept.

Answer 4

For the \(y-intercept\), you replace \(x\) with 0. Can you continue?

Answer 5

got it

Answer 6

All right then =)
