Answer:
I took a pic, if it helps
X + 3 = 0 is not a function because it is a vertical line.
A vertical line has undefined slope because all points the line have the same x-coordinate.
A function is a relation in which no two ordered pairs have the same first component (x-values or input) and different second components (y-values or output).
Remember that a function can only take on one output for each input. Since a vertical line has the same x-coordinates for all values of y-coordinates, then it means that it is not a function.

Answer:
C
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (4, - 1) ← 2 points on the line
m = =
note that the line crosses the y-axis at (0, - 2) ⇒ c = - 2
y = x - 2 ← equation of line
