Question

What is the equation of the line that passes through (0, -2) and has a slope of 0?

A. y = -2
B. y = 2
C. x = 2?

Answer 1

so (0,-2) equals (x,y) and if the slope is 0 it will be a vertical line. Therefore, the equation is y=-2. Not y=2 since it's a negative.

Answer 2

Jeleena if it has to pass through 0,-2 why would there be a line going through positive 2

Answer 3

\(\bf \begin{array}{lllll}
&x_1&y_1\\
&({\color{red}{ 0}}\quad ,&{\color{blue}{ -2}})\quad
\end{array}
\\\quad \\

slope = {\color{green}{ m}}= 0
\\ \quad \\

y-{\color{blue}{ y_1}}={\color{green}{ m}}(x-{\color{red}{ x_1}})\qquad \textit{plug in the values and solve for "y"}\\
\qquad \uparrow\\
\textit{point-slope form}\)
