1. Find the equation of the line that is parallel to the line y = 3x + 9 and passes through the<br />
point (–4, 3). Write your answer in point-slope form. [ y ! 3 = 3(x + 4) ]<br />
2. Find the equation of the line that is parallel to the line y = 2x + 8 and passes through the<br />
point (–4, 3). Write your answer in slope-intercept form. [ y = 2x + 11 ]<br />
3. Find the equation of the line that is parallel to the line y = !6x ! 8 and passes through the<br />
point (8, 3). Write your answer in point-slope form. [ y ! 3 = !6(x ! 8) ]<br />
4. Find the equation of the line that is parallel to the line y = !5x ! 9 and passes through the<br />
point (7, 1). Write your answer in slope-intercept form. [ y = !5x + 36 ]<br />
5. Find the equation of the line that contains the points (1, 7) and (–5, –3). Write your answer<br />
in slope-intercept form. [ y = 5 3 x + 16 3 ]<br />
6. Find the equation of the line that contains the points (–5, –10) and (9, 6). Write your<br />
answer in slope-intercept form. [ y = 8 7 x ! 30 7 ]<br />
7. Find the equation of the line that contains the points (–1, 4) and (–5, –4). Write your<br />
answer in point-slope form. [ y ! 4 = 2(x + 1) or y + 4 = 2(x + 5) ]<br />
8. Find the equation of the line that contains the points (5, 2) and (8, 11). Write your answer<br />
in point-slope form. [ y ! 2 = 3(x ! 5) or y ! 11 = 3(x ! 8) ]<br />
9. Find the equation of the line that is perpendicular to the line y = 7x + 1 and passes through<br />
the point (3, –1). Write your answer in point-slope form. [ y + 1 = ! 1 7 (x ! 3) ]<br />
10. Find the equation of the line that is perpendicular to the line y = 6x + 2 and passes through<br />
the point (3, 7). Write your answer in slope-intercept form. [ y = ! 1 6 x + 15 2 ]<br />
11. Find the equation of the line that is perpendicular to the line y = !9x ! 8 and passes<br />
through the point (1,6). Write your answer in slope-intercept form. [ y = 1 9 x + 53<br />
9 ]<br />
12. Find the equation of the line that is perpendicular to the line y = 2x + 5 and passes through<br />
the point (–6, –7). Write your answer in slope-intercept form. [ y = ! 1 2 x ! 10 ]<br />
