Question

1. This table represents a relationship between x and y, where x is the independent variable.

x 1 2 3 4 5
y 3 4 5 6 7
Which equation represents the relationship between x and y?

x = 2y


x = y + 2


y = 2x


y = x + 2

2. This table represents a relationship between x and y, where x is the independent variable.

x 9 12 15 18 21
y 3 6 9 12 15
Which equation represents the relationship between x and y?

y=x−6


y = 3x


y = x + 6


y=13x

3. This table represents a relationship between x and y, where x is the independent variable.

x 9 12 15 18 21
y 3 4 5 6 7
Which equation represents the relationship between x and y?

y = x + 6


y=x−6

y = 3x


y=13x

Answer 1

1 =x+2

2 =y+6

3 y=3x

Explanation:

1 x+2 if x=1

1+2=3

2+2=4

3+2=5
