Answer 1

`A' = (-1,6)`

`B'= (-3,1)`

`C' = (-7,2)`

Explanation:

Given

`A = (1,6)`

`B = (3,1)`

`C = (7,2)`

Required

Reflect over the y-axis

When a point is reflected over the y-axis, the rule is:

`(x,y)=>(-x,y)`

So, points ABC becomes:

`A = (1,6)`

`B = (3,1)`

`C = (7,2)`

`A' = (-1,6)`

`B'= (-3,1)`

`C' = (-7,2)`
