Whats the difference between reflectional and rotational symmetry?

Reflection reflect exactly like on a lake you see the reflection that wold be reflection across the x-axis rotational rotates like a clock

I’m going to infer you said parallel.solve for yy= -1/2x+7/4lines that are parallel have the same slope, different y intercept.so we know m is -1/2then from there solve for y intercept.
