somebody help me out

Answer:
Equation is y = 3
Step-by-step explanation:
[tex](x_1, y_1) = ( -2, 3) \ , \ (x_2, y_2) = (8, 3 )[/tex]
[tex]Slope,m = \frac{y_2 - y_1}{x_2-x_1} = \frac{3-3}{8 -- 2} = 0[/tex]
[tex]Equation : (y - y_1) = m (x - x_1)[/tex]
[tex]y - 3 = 0 (x -- 2)\\y - 3 = 0\\y = 3[/tex]
