ILL SOMEONE PLEASE HELP ME WITH ALL OF THESE^^^

OpenStudy (anonymous):

One at a time please.

OpenStudy (anonymous):

will you please just help me with them one at a time

OpenStudy (anonymous):

I will help with one, then you can try the rest. First important thing to know is that parallel lines have the same slope, and perpendicular lines have 'opposite-reciprocal' slope. For example, if the first line has a slope of 1/3, the perpendicular line has a slope of -3.

For your first question, "1. Write the equation of the line which passes through (5, –2) and is parallel to x = 4. " It's a vertical line, so your equation also has to be x = something. What is x there?

Write the equation of the line which passes through (5, –2) and is parallel to x = 4. For line parallel to x=4, it is a vertical line. A vertical line has only x-intercept so it is x=5
