Question

Write an equation of each line

Answer 1

y = x - 3

3y = 2x + 3

y = -x - 1

Explanation:

19. Slope = (1 - -2) / 6 - 3) = 1

y - y1 = 1(x - x1)

y - -2 = 1(x - 1)

y + 2 = x - 1 so y = x - 3 Answer

20. slope = 2/3 and y intercept = 1 so its

y = 2/3x + 1

or 3y = 2x + 3

21. Slope = -1 and y-intercept = -1, so its

y = -x - 1

Answer 2

20. Y=2/3x+1
21. Y=1x-1
