The line of symmetry is involved in reflection transformations- when you reflect a graph, you can see the line that separates the original image from its reflected one.
This line acts as a line of symmetry because it divides the mirror images.
y-step explanation:
4×30+5×30=120+150=270
looking at the last row, we can see that the total number of students will be 4×30+5×30=120+150=270
