Question

Write the equation of the mirror line for the segment with endpoints (3, 0) and (-5, -2).

answers shown in picture.

Answer 1

The Ans is B

i.e y=(1/4)x-3/4

Explanation:

Given points (3,0) and (-5,-2)

Slope m=(y2-y1)/(x2-x1)

So m=(-2-0)/(-5-3)

=-2/-8

i.e 1/4 or 0.25

Equation of line when two points are given

y-y1=m(x-x1)

Therefore

y-0=0.25(x-3)

y=x/4-3/4

i.e y=(1/4)x-3/4
