Answer:
Equation of line:
Step-by-step explanation:
We have given,
Slope of line =
y intercept equal to that of a line y =
i.e, y intercept = -2 {Plug x = 0 in the line equation}
Hence we have a slope = and y intercept = -2.
That means , equation of line will be formed as:
And we can also plot this line on a graph.

Answer:
No. This graph does not represent a function.
Step-by-step explanation:
Functions have one output for each input. For example;
(1, 3) (2, 6) (3, 9) etc.
This is not a function because the same input has multiple outputs;
(-5, 1) (-5, 2) (-5, 3) etc.
