Find an equation for each of the lines described below. Homework Help ✎

  1. The line with slope that goes through the point .

    Use slope-intercept form.

  2. The line parallel to that goes through the point .

    Parallel lines have the same slope. Use the point-slope form of the equation of a line.

  3. The line perpendicular to that goes through the point .

    The slopes of perpendicular lines are opposite reciprocals.

    For example,  and 

  4. The line that goes through the point so that the tangent of the angle it makes with the x-axis is 2.

    Remember the trigonometric relationships.

    How might tangent's relationship to the opposite and adjacent sides relate to the rise and run of the slope?
