Geometry help needed.

Margaret [11]

A'B'C' is larger than ABC, so the scale factor would be a whole number, scale factor of 2.

A'B'C'is also a morrir image of ABC, notice on ABC A is on the left and B is on the right, but on A'B'C', B" is on the left and A' is on the right.

This means it was reflected across the Y axis.

The first answer is the correct one.

Someone please please help me with this math problem I’m really bad at graphs

nataly862011 [7]

Answer:

$y + 2 = - (x - 4)$

Step-by-step explanation:

The graph passes through: (0,2) and (2,0)

The slope is

$\frac{0 - 2}{2 - 0} = - 1$

The equation of the line in point-slope form is given by:

$y-y_1=m(x-x_1)$

The graph passes through (4,-2).

We substitute the slope and this point to get:

$y - - 2 = - 1(x - 4)$

$y + 2 = - (x - 4)$

The first option is correct
