Determine the slope of a every line that is parallel to the
Determine the slope of (a) every line that is parallel to the given line and (b) every line that is perpendicular to the given line.
y = -3x + 2
| a. | (a) m = -3 (b) m = 1/3 | b. | (a) m = 1/3 (b) m = -3 |
|---|---|---|---|
| c. | (a) m = -3 (b) m = -1/3 | d. | (a) m = -1/3 (b) m = -3 |
Solution
the line is of the form y=mx+c where m is the slope of line
m =-3
for parallel m=-3
for perpendicular sllope = -1/m = 1/3
option A) is the answer
