Write equations...
6. If the slope of a line is -4 and the line goes through the point (-1, 9) express the equation of this line in slope-intercept form.
y = -4x + 5
7. What is the equation of a line through the point (2, -5) that has a slope of 10?
y = 10x - 25
8. What is the equation of the line through the point (-2, -17) that has a slope of -7?
y = -7x - 31
9. If the slope of a line is -2 and the line goes through the point (-1, -3) express the equation of this line in slope-intercept form.
y = -2x - 5
12. What is the equation of a line through the point (12, -2) that has a slope of ¾ ?
y = 3/4x - 11
10. What is the equation of a line through the point (4, 6) that has a slope of ½ ?
y = 1/2x + 4
11. What is the equation of a line through the point (-3, -5) that has a slope of -⅔ ?
y = -2/3x - 7
13. What is the equation of a line through the point (-12, -5) that has a slope of -⅚ ?
y = -5/6x - 15
14. What is the equation of a line through the point (-200, -500) that has a slope of -3/100?
y = -3/100x - 506
15. What is the equation of a line that passes through the points (3, -4) and (5, -6)
Hint: 1st find slope. Then use the skill you practiced today.
y = -1x - 1 (or y = -x - 1)
