Answer:
Domain is all the x values which return a y value.
Range is all the y values that can be returned from any given x.
For example, y=x^2 has a domain of all real numbers because any number can be squared and get another number, however it has a range of y>=0 because no matter what x no value under 0 can be returned.

Answer:
Use two of the points
Step-by-step explanation:
use the equation y=mx+b and plug the numbers in
Let’s use (1,0)
0 = -4x1+b (multiply)
0=-4+b (bring the three on the other side)
-4= b
Y= -4x-4
To find slope use 2 points on the graph and do [tex]\frac{Y2-Y1}{X2-X1}[/tex]
Which means points 1 and points 2
Let’s use (1,0) y1 x1 and (0,-4) y2 x2
[tex]\frac{-4-0}{0-1}[/tex]= -4
