Anastasia Ayers · Answer 1

Y = x - 13

x = - 3

Since the value of x has already been given, we can substitute its value to the x in the 1st equation.

y = x - 13

= - 3 - 13 * both carry the same negative signs, so addition is performed but the sign is carried over to its sum

y = - 16

(-3,-16)

Chico · Answer 2

Y=-3-13 y=-16 you add - 3 to - 13 to get - 16

Evaluate:y = x - 13 when x = - 3.

Evaluate:

y = x - 13 when x = - 3.
