Parallel and perpendicular slope

Determine whether the statement is always, sometimes, or never true. Explain your reasoning.

A vertical line is parallel to the y​ -axis.

Two distinct nonvertical lines that have the same slope are

Count rise over run. Which two lines are parallel?

Determine which of the lines, if any, are parallel. Explain.

Line a passes through (-1, -2) and (1, 0)

Line b passes through (4, 2) and (2, -2)

Line c passes through (0, 2) and (-1, 1)

Determine which of the lines, if any, are parallel. Explain.

Line a: 4y + x = 8

Line b: 2y + x = 4

Line c: 2y = -3 + 6

Write an equation of the line that passes through (−1,3)​ and is parallel to the line y=2x+2​ .

Write an equation of the line that passes through (18, 2)​ and is parallel to the line

3y - x = -12

Correct the error in writing an equation of the line that passes through (1, 3)  and is parallel to the line $$y\ =\ \frac{1}{4}x\ +2$$ .
