Question

plot the point on the line with the x-coordinate x = -9

Answer 1

Substituting x=-9 in the given equation we get:

$-4(-9)+y-38=0.$

Simplifying the above result, we get:

$\begin{gathered} 36+y-38=0, \\ y-2=0. \end{gathered}$

Adding 2 to both sides of the equation, we get:

$\begin{gathered} y-2+2=0+2, \\ y=2. \end{gathered}$

Therefore, the coordinates of the point with x=-9 are:

$(-9,2)\text{.}$
