5 because -2+5=3 explanation
Answer:
{x,y} = {-1,-9}
Step-by-step explanation:
For this case we have by definition, that the equation of a line in the slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cutoff point with the y axis
We need two points through which the line passes to find the slope:

We found the slope:

So, the equation is of the form:

We substitute a point to find "b":

Finally, the equation is:

Answer:
Option D
Plug one intercepts: (-1)^2+(-1)b+5=0
(-5)^2+(-5)b+5=0
simplify: 6-b=0
30-5b=0
solve for b: 6=b
30/5=b
