Answer:
the second option is the correct one
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
To calculate m use the slope formula
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (7, 5) and (x₂, y₂ ) = (- 4, - 1)
m =
=
= 
Use either of the 2 points as (a, b)
using (- 4, - 1), then
y- (- 1) =
(x - (- 4)), that is
y + 1 =
(x + 4)
I believe the answer would be C; but I'm not sure if this is the right category for this question?

Answer:
<em>Neither A nor B</em>
Step-by-step explanation:
Neither set of order pairs represent a function, because none of the points have a correlating function throughout them.
