Question

Tasha wants to graph a line that is parallel to the line with equation y=3x. Give two examples of linear equations that represent lines she should draw: one that us above the original line and one that is below the original line

Answer 1

y=3x+1 and y=3x-1

Explanation:

y=3x+1 is above because it has a positive slope (3) while y=3x-1 is below because it has a negative slope (-3).

Answer 2

y = 3x + a (a > 0) - above the original line

y = 3x + b (b < 0) - below the original line

Explanation:

Pick any number you want for a or b, as long as the number meets the condition I wrote down.
