Answer:

last option: y = (-2/3)x + 5

Explanation:

slope-intercept equation: y = mx + b

where m is the slope and b is the y-intercept

if slope m = -2/3, then y = (-2/3)x + b

if point (3, 3) is on the line, substitute x=3 and y=3 into the equation and solve for b:

3 = (-2/3)3 + b

⇒ 3 = -2 + b

⇒ b = 5

Therefore, equation: y = (-2/3)x + 5
