Step-by-step explanation:
Given the equation
Putting x = -2 in the equation
y = 2x + 3
= 2(-2) + 3
= -4 + 3
= -1
(x, y) = (-2, -1)
Putting x = -1 in the equation
y = 2x + 3
= 2(-1) + 3
= -2 + 3
= 1
(x, y) = (-1, 1)
Putting x = 0 in the equation
y = 2x + 3
= 2(0) + 3
= 0 + 3
= 3
(x, y) = (0, 3)
So the table chart of x and y values will be:
x y
-2 -1
-1 1
0 3
