1. Graph each of the following equations by finding the x-intercept and y-intercept. 5x + y − 10 = 0
−x − y − 1 = 0
2.Use your knowledge of point-slope form to graph each of the following equations.
y − 2 = −3(x − 1)
y = 12 (x − 1)

3.Use the point-slope formula to determine the equation of the line that has a slope of
1⁄2 and passes through point (0, 0).

4.Use the point-slope formula to determine the equation of a line that passes through
the points (1, 2) and (–2, 1).
