Question

b2
reflect the coordinates from b over the y - axis.
state the new coordinates below.
new x
new y

Explanation:

Step1: Recall the reflection rule over y - axis

When reflecting a point \((x,y)\) over the \(y -\)axis, the rule is \((x,y)\to(-x,y)\).

Step2: Apply the rule to each point

• For the point \((3,8)\):

Using the rule \((x,y)\to(-x,y)\), when \(x = 3\) and \(y=8\), the new \(x\) is \(-3\) and \(y\) remains \(8\).

• For the point \((6,5)\):

Using the rule \((x,y)\to(-x,y)\), when \(x = 6\) and \(y = 5\), the new \(x\) is \(-6\) and \(y\) remains \(5\).

• For the point \((7,-11)\):

Using the rule \((x,y)\to(-x,y)\), when \(x=7\) and \(y =- 11\), the new \(x\) is \(-7\) and \(y\) remains \(-11\).

Answer:

For the point \((3,8)\): New \(x=-3\), New \(y = 8\); For the point \((6,5)\): New \(x=-6\), New \(y = 5\); For the point \((7,-11)\): New \(x=-7\), New \(y=-11\)
