Tables, points and y = mx + c
Complete tables of values, plot points and connect gradient and intercept to a straight line.
Example 1
Complete the missing y−value in the table for y=x−2.
Table of valuesShow worked answer
Answer: 0
- Substitute x=2 into y=x−2.
- y=1×(2)+(−2)=0.
Example 2
Complete the missing y−value in the table for y=x−1.
Table of valuesShow worked answer
Answer: −3
- Substitute x=−2 into y=x−1.
- y=1×(−2)+(−1)=−3.
Example 3
For y=2x−2, find the point where x=−3 and plot it.
Show worked answer
Answer: (−3,−8)
- Substitute x=−3:y=2×(−3)+(−2)=−8.
- Write the horizontal coordinate first, then the vertical coordinate: (−3,−8).
