Plz help with 20-22 thank you

#20 = 13

#21 = 1

#22 = -3

Step-by-step explanation:

Replace all of the x values in the equations for the one in the table.

Then solve.

This is the equation

Y= -4x - 3

A. x = -4

Replace x with -4.

   Y = -4 (-4) - 3

Solve.

   Y = 16 - 3

   Y = 13

#20 = 13

B. x = -1

Replace x with -1

   Y = -4 (-1) - 3

Solve.

   Y = 4 - 3

   Y = 1

#21 = 1

C. x = 0

Replace x with 0.

   Y = -4 (0) - 3

Solve.

   Y = 0 - 3

   Y = -3

#22 = -3
