Answer:

y1 = -5

y2 = -1

y3 = 5

y4 = 9

Explanation:

The equation of the table is

y = 2x - 5

The table is

→ x → y

→ 0 → y1

→ 2 → y2

→ 5 → y3

→ 7 → y4

To complete the table by finding the values of y substitute every x in the equation by its value to find the corresponding y

∵ y = 2x - 5

x = 0

→ Substitute x by 0

∴ y1 = 2(0) - 5

∴ y1 = 0 - 5

y1 = -5

∵ y = 2x - 5

x = 2

→ Substitute x by 2

∴ y2 = 2(2) - 5

∴ y2 = 4 - 5

y2 = -1

∵ y = 2x - 5

x = 5

→ Substitute x by 5

∴ y3 = 2(5) - 5

∴ y3 = 10 - 5

y3 = 5

∵ y = 2x - 5

x = 7

→ Substitute x by 7

∴ y4 = 2(7) - 5

∴ y4 = 14 - 5

y4 = 9
