Answer:

Below!

Step-by-step explanation:

Since there is a variable (x) on the L.H.S and a constant (-7) on the R.H.S, the line will be a vertical line intersecting the x-coordinate (-7).

~Graph attached

<u>Determining the y-intercept of the line:</u>

Since the line is a vertical line, it's y-intersept is undefined as it will never intersect the y-axis.

<u>Determining the slope of the line:</u>

To determine the slope of the line, pick any two points that is <u>on</u> the line.

  • ⇒ (-7, 0) and (-7, 1)

Using the slope formula (y₂ - y₁/x₂ - x₁):

  • ⇒ 1 - 0/-7 - (-7)
  • ⇒ 1/-7 + 7
  • ⇒ 1/0

∴ Any number divided by 0 is undefined

  • ⇒ underfined

Thus, the slope and the y-intercept are undefined.
