Question

Write an equation of each line

Answer 1

Answer:

y = x - 3

3y = 2x + 3

y = -x - 1

Step-by-step 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
