Anybody know how to do this

See explanation below

Step-by-step explanation:

Plug in each x value into the equation to calculate the y value.

a) 2x + 3y = 6

x = 0, y = 2

x = 1.5, y = 2/3

x = 3, y = 0

b) y + 2x = 0

x = -1, y = 2

x = 0, y = 0

x = 2, y = -4

c) x - 2y = 0

x = 0, y = 0

x = 2, y = 1

x = 4, y = 8

d) 3x - y = 3

x = 0, y = -3

x = 1, y = 0

x = 2, y = 3

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
