What is the equation of the line that is parallel to the line x = –2 and passes through the point (–5, 4)?x = –5x = 4y = –5y = 4
Rainbow [258]

x = -5 is the equation of the line that is parallel to the line x = –2 and passes through the point (–5, 4)

<em><u>Solution:</u></em>

Given that, we have to write the equation of line that is parallel to line x = -2 and passes through point (-5, 4)

From given,

The equation of the line in standard form is x = -2

<em><u>This is a vertical line, so the parallel line will also be a vertical line of the form:</u></em>

x = a

Since we are given that the line should pass through the point (-5, 4)  then the equation of the line is:

x = -5

Thus the equation of line is found
