Write an equation of a line that is parallel to the line

y = x - 5 and goes through (1, -2) - Use the steps from 3.5 Geometry Journal

• y = -3x +1

• y = x - 3

• y = x + 1

• y = 3x +1

Identify the slope of a line parallel to the one graphed. (Hint: You can count rise/run, or use the slope formula: (y - y) / (x - x)
