Graphing made easy - Point-Slope (3.7)
1. Explain how the point-slope equation is similar to the slope-intercept equation.
2. Explain how the point-slope equation is different than the slope-intercept equation.
3. For the following POINT-SLOPE equations, do the following:
a) Determine the slope
b) Determine the given point.
c) Use this information to graph the line.
d) Use your graph to help you locate the y-intercept.
A) B)
C) D)
E) F)
4. Change all the point-slope equations above, to slope-intercept equations. Does the y-intercept match up with your work we did in the work above?
