Question

what is the equation of a horizontal line that passes through the point (-2, 5)x= -2 x = 5y = -2y = 5

Answer 1

An horizontal line has slope equal to zeto, that is m=0.

Then using the equation of a line:

`y-y_1=m(x-x_1)`

we have:

`\begin{gathered} y-5=0(x-(-2)) \\ y-5=0 \\ y=5 \end{gathered}`

Therefore the answer is the last option.
