Kanika plots point A at (1, -2). Next she plots a reflection of point A at point W. Finally, Kanika plots a
reflection of point Wat point T, which is located at
(-1, 2). Describe how Kanika could have reflected each
of the points to arrive at point T.

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
