1. Find an equation of the straight line that passes through the point (1, 4) and is parallel to the line passing through the points (3, 4) and (2, 1). (Let x be the independent variable and y be the dependent variable.)

2. Find an equation of the line that passes through the point (5, 4) and is perpendicular to the line

4x + 5y 8 = 0.

3. Find an equation of the line that passes through the points. (Let x be the independent variable and y be the dependent variable.)
