Which equation is written in STANDARD form?

• y = 1/2x + 2

• y - 3 = -5(x + 2)

• 7x - 2y = -9

• 3x + 2 = y

Write the standard form equation that passes through (0, -1) and (-6, -9)

• 4x - 3y = 4

• 4x - 3y = 3

• -4x +3y = 5

• 4x - 3y = -10

Rewrite the equation into Standard form

• 5x + 8y = 56

• -5x + 8y = 56

• 8x + 5y = 56

• 5x + y = 7
