Answer:
(5, 4) is correct.
First comes x, which is horizontal on the graph
Then comes y, which is vertical.
To get a perpendicular line, your slopes will equal -1 when multiplied...this means if we multiply - 4 x (1/4), we get out slope to use for the next step.
Y - Y1 = M(X - X1) passes through (-2, 7)
Y - 7 = 1/4(X - (-2))
Y - 7 = 1/4(X + 2)
Y - 7 = 1/4X + 1/2
+7 + 7
Y = 1/4X + 7.5
Answer:
The dialation is of 2
Step-by-step explanation:
QR = 3 units
QS = 2 units
RS = 2 units
Q'R' = 6 units
Q'S' = 4 units
R'S' = 4 units
So as you can see, this triangle has doubled it's size, since it has been multiplied by 2.
Hope this helped!
