Question

Write the slope intercept form:through: (5, 1), perp. to x= -1

Answer 1

$\begin{gathered} \text{the line must be perpendicular to x=-1 which has m=infinity. Hence the line we wants must have slope equal zero.} \\ \text{And this lines must pass through (5,1), hence, the equations is y=1} \end{gathered}$
