Look at the adjoining figure and write 2 pairs of intersecting lines.

Concept:

Intersecting lines are lines that overlap upon only one point. The number of lines can be two or more.

Intersecting lines can intersect at any angle.

Solve:

There are in total four intersecting points in the given figure.

As we can see from the figure, any two lines would intersect each other

Therefore, 2 pairs of intersecting lines can be any pairings of lines that are not in the same orientation.

Hope this helps!! :)

B:Both powers should be in the denominator with positive exponents.

Step-by-step explanation:

We are given that Tyler simplified an expression

We have to find an error which Tyler makes in her simplification

Step 1:

Step 2:

Step 3:

Hence, Tyler's error is both exponents should be denominator with positive exponents.

B:Both powers should be in the denominator with positive exponents.
