Question

For each of the following, write the equation of the line determined by the given pair of points in slope-intercept form or in the form x-a or y-b

a. (3.5) and (3, 1)
b. (0.0) and (3,5)
c. (0,4/5) and (4/5,0)
d. (0, 2) and (5, 2)

Answer 1

Explanation:

See the two attachments.

Set up a spreadshhet to calculate the rise and run for each line. The rise is the change in y and the run is the change in x between two pints. See FindEquations. All the points are set up so that the Rise and Run can be calculated for each set of points (A,D,C, and D). Slope is Rise/Run and is noted in the column with the red arrow. The first line has an infinite slope (#######).
