Answer:
QR ≈ 16.3
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
= , substitute values
= ( cross- multiply )
57 QR = 926.9 ( divide both sides by 57 )
QR ≈ 16.3 ( to the nearest tenth )
The slope is 3 and it's positive
(2, 5) and (3, 8)
m=(y2-y1)/(x2-x1)
m=(8-5)/(3-2)
m=3/1
m=3
its red
0y225
