After a rotation of 90° about the origin, the coordinates of the vertices of the image of a triangle are A'(6,3), B'(-2, 1)

Fed [463]

Answer:

A(3, -6)
B(1, 2)
C(7, -1)

Step-by-step explanation:

Rotation by -90° about the origin is the transformation ...

(x, y) ⇒ (y, -x)

So, your pre-image points are ...

A'(6, 3) ⇒ A(3, -6)

B'(-2, 1) ⇒ B(1, 2)

C'(1, 7) ⇒ C(7, -1)

Abigail and Spencer calculate the slope of the line between the points (3,-1) and (5,4) in different ways. Abigail calculates th

telo118 [61]

Answer:

Spencer and Abigail are correct

Lauren is incorrect

Step-by-step explanation:

Spencer and Abigail are correct

Slope = change in y ÷ change in x

Or $m=\dfrac{y_2-y_1}{x_2-x_1}$

Let $(x_1,y_1)$ = (3, -1)

Let $(x_2,y_2)$ = (5, 4)

$\implies m=\dfrac{4-(-1)}{5-3}=\dfrac52$

This is Spencer's method

Let $(x_1,y_1)$ = (5, 4)

Let $(x_2,y_2)$ = (3, -1)

$\implies m=\dfrac{-1-4}{3-5}=\dfrac52$

This is Abigail's method

It doesn't matter which point you label as point 1 and point 2, as long as you carry out the slope calculation correctly.

Lauren's calculation is wrong as she calculated her slope as:

$m=\dfrac{y_2-y_1}{x_1-x_2}$

where it should have been $m=\dfrac{y_2-y_1}{x_2-x_1}$
