Slope of the line passing through the points(-2,9) and (7,9)

Question

that it i need the answer now plz

Answer 1

slope = 0

the y value remains constant. That's a line with flat horizontal slope = 0

Or use the formula for slope = "rise over run" = the change in y coordinates divided by the change in corresponding x coordinates = (9-9)/(7- -2) = 0/9 = 0
