Explanation:

Step1: Analyze number 2

Check if a vertical/horizontal line divides 2 into two mirror - image halves. A vertical line doesn't, and a horizontal line also doesn't create two identical mirror - image parts. So 2 does not have line symmetry.

Step2: Analyze number 3

Draw a horizontal line through the middle of 3. The upper and lower parts are mirror images of each other. So 3 has line symmetry.

Step3: Analyze number 4

Check for a line that can divide 4 into two mirror - image halves. Neither a vertical nor a horizontal line (or any other line) can create two identical mirror - image parts. So 4 does not have line symmetry.

Step4: Analyze number 7

Check for a line of symmetry. No line can divide 7 into two mirror - image halves. So 7 does not have line symmetry.

Step5: Analyze number 8

Draw a horizontal or vertical line through the middle of 8. In both cases, the two parts are mirror images of each other. So 8 has line symmetry.

Step6: Analyze number 9

Check for a line of symmetry. No line can divide 9 into two mirror - image halves. So 9 does not have line symmetry.

Answer:

The numbers with line symmetry are 3 and 8 (the figure of 3 and the figure of 8).
