Question

Choose the equation of the horizontal line that passes through the point (4, -3).

y = 4

x = -3

x = 4

y = -3

Answer 1

We know a horizontal line always has equation y=a. In this case, if the horizontal line passes through the point (4, -3), the equation must be y=-3 as the horizontal line will only ever hit one y-value. Since it must hit this point, thus a y-value of -3, it's equation is simply that: y=-3! :)

Answer 2

thank you :)
