First try was incorrect Write the equation of a line that passes through the point (-10, 9) and
is parallel to the y-axis.

x=-10

Step-by-step explanation:

If the equation is parallel to the y axis then it must be vertical. Only way for the equation to be vertical is by x= ?. If the equation must pass through (-10,9) then you would use the x value of this coordinate which is -10.

Red line is the y axis and the blue line is the line that passes through (-10,9)
