Yr 8 Unit 4 week 1 - Lesson 2

Explain what y = x means

If y = 2x, select the correct coordinate

1. (2, 0)
2. (0, 2)
3. (1, 2)
4. (2, 1)

If y = 2x + 1, select the correct coordinate

1. (0, 0)
2. (0, 2)
3. (1, 2)
4. (2, 5)

If y = 1 - 2x, select the correct coordinate

1. (0, 0)
2. (0, 1)
3. (1, 2)
4. (2, 3)

If x + y = 9 and x =
what is the value of y

√​16​​​

1. 2
2. 3
3. 4
4. 5

If x + y = 3 and x = -1
what is the value of y?

1. 2
2. 3
3. 4
4. 5

y  = x + 1

y = 2x + 3

y = 2x + 4 

y = 2x + 5 

Drag and drop the coordinate pair  that satisfies each of the linear equations.

(0, 1)

(0, 5)

(0, 3)

(0, 4)

y  = 2x + 1

y = -2x + 3

y = -2x + 1 

y = 2x + 3 

Drag and drop the coordinate pair that satisfies each of the linear equations when x = 2.

(2, -3)

(2, -1)

(2, 5)

(2, 7)

Explain the purpose of a coordinate pair such as (2, 1)
