complete the table of values for y=2x+3?

Question

x -2 -1 0 1 2 3
y- - 1 3 - - -

Answer 1

y = 2x + 3

so for x = -2

y = 2(-2) + 3 = -4 + 3 = -1

for x = -1

y = 2(-1) + 3 = -2 + 3 = 1

for x = 0

y = 2(0) + 3 = 0 + 3 = 3

for x = 1

y = 2(1) + 3 = 2 + 3 = 5

for x = 2

y = 2(2) + 3 = 4 + 3 = 7

for x = 3

y = 2(3) + 3 = 6 + 3 = 9

Answer 2

x = -2 , -1, 0, 1, 2, 3

y = -1, 1, 3, 5, 7, 9

Answer 3

The corresponding y's are: -1, 1, 3, 5, 7, 9.
