Write the equation in the form y = mx + b.

Question

27. 7x + y = 10

28. 2x + 7y = 14

29. 2x − 9y = 18

30. x − 4y = 12

Answer 1

These are all worked the same way. I will do one as an example, and you try the rest.

(29)

2x - 9y = 18

Solve for y.

-9y = -2x + 18

y = (-2/-9)x + 18/(-9)

y = (2/9)x - 2

m = 2/9

b = -2
