Question

Write the equation of the line which passes through (5, –2) and is parallel to x = 4. (1 point)

Write the equation of the line which passes through (2, 1) and is perpendicular to x = –2. (1 point)

Write the equation of the line which passes through (–4, 2) and is parallel to y = –x + 6 in slope-intercept form. (2 point)
Write the equation of the line which passes through (2, –3) and is perpendicular to y = 4x + 7 in standard form. (2 point)

Using complete sentences, describe one example of a place in your everyday life of parallel lines and one example of perpendicular lines.

Answer 1

Parallel lines have the SAME slope.

Answer 2

x = 4 has an UNDEFINED slope

Answer 3

Is there no answer to the first one then..?

Answer 4

Well you can just write an equation that is also x = ?.

It will pass through all it's possible y values so really it's just x = given x value.

Answer 5

Since x = 4 is just a line passing through x and every y value for it.
