Question

1. type your answer the correct way. do not include letters. do not leave spaces. 14. point j (-8, -12) is reflected over the x - axis. where is j’? (8,-12) 15. type your answer the correct way. do not include letters. do no leave spaces. 15. point w(-6, 7) is rotated 90° clockwise. where is w’?

Explanation:

Step1: Recall reflection rule over x - axis

When a point $(x,y)$ is reflected over the x - axis, the rule is $(x,y)\to(x, - y)$. Given point J$(-8,-12)$, applying the rule, the x - coordinate remains the same and the y - coordinate changes sign. So J' is $(-8,12)$.

Step2: Recall 90 - degree clockwise rotation rule

The rule for rotating a point $(x,y)$ 90 degrees clockwise about the origin is $(x,y)\to(y,-x)$. For point W$(-6,7)$, substituting $x = - 6$ and $y = 7$ into the rule, we get $W'=(7,6)$.

Answer:

1. (-8,12)
2. (7,6)
