Triangle PQR is transformed to triangle P'Q'R'. Triangle PQR has vertices P(4, 0), Q(0, −4), and R(−8, −4). Triangle P'Q'R' has vertices P'(1, 0), Q'(0, −1), and R'(−2, −1).
Plot triangles PQR and P'Q'R' on your own coordinate grid.
Part A: What is the scale factor of the dilation that transforms triangle PQR to triangle P'Q'R'? Explain your answer. (4 points)
Part B: Write the coordinates of triangle P"Q"R" obtained after P'Q'R' is reflected about the y-axis. (4 points)

Have you plotted the triangles?
OpenStudy (piercetheveil47):
no :(
OpenStudy (piercetheveil47):
I'm like soooo confused
OpenStudy (mathstudent55):
Do you know how to plot points on a coordinate grid?
OpenStudy (piercetheveil47):
yes

but the question doesn't even plot anything ):
OpenStudy (mathstudent55):
Before part A, it asks to plot the two triangles.
OpenStudy (piercetheveil47):
you're right
OpenStudy (piercetheveil47):
but its too confusing
OpenStudy (piercetheveil47):
like i suck at this I'm going to fail i swear

If you take one part at a time, it's not hard.
The first step is to plot both triangles.

Ok, there is my grid. Now we need to plot the points of both triangles and label them.
