Question

I'm needing help with graphing equation

Answer 1

what is the equation?

a) y = 2x

x y

1 2(1) = 2

2 2(2) = 4

3 2(3) = 6

4 2(4) = 8

5 2(5) = 10

b) y = x - 2

x y

2 2 - 2 = 0

3 3 - 2 = 1

4 4 - 2 = 2

5 5 - 2 = 3

6 6 - 2 = 4

a) line a

line b

c)

y = 3x + 2

x y

1 3(1) + 2 = 5

2 3(2) +2 = 8

3 3(3) + 2 = 11

4 3(4) + 2 = 14

5 3(5) + 2 = 17

line d

y = 5x - 3

x y

0 5(0) - 3 = -3

2 5(2) - 3 = 7

4 5(4) - 3 = 17

6 5(6) - 3 = 27
