Question 700142: write an equation in slope intercept form of the line that passes through the given point and is parallel to the graph of the given equation. (4,2) x = -3

No can do.  is a vertical line, hence any line parallel to it must also be vertical. All vertical lines have an undefined slope, so you cannot write an equation in slope-intercept form if the slope number is undefined. Also, with the exception of the line  , all vertical lines are parallel to and do not intersect the  -axis. This means that the -intercept does not exist or, in the singular case of , there are infinite -intercepts so the -coordinate of the -intercept would be impossible to uniquely specify in a slope-intercept form equation.
However, you can write an equation, albeit not in slope-intercept form, that represents the desired line. An equation for ANY vertical line is of the form  where  is the  -coordinate of any point through which the line passes. Since you are given the point ) you have enough information to write the desired equation.
