Answer:
on #1 x=2 and y=2
Step-by-step explanation:
a squared + b squared = c squared
2 squared + 2 squared = 4 squared
4 + 4 = 8
Given:
The coordinates of point A are (7,4).
It is dilated from the origin by a scale factor r = 3.
To find:
The coordinates of A'.
Solution:
If a figure is dilated from the origin by a scale factor k, then

Here, the figure is dilated from the origin by a scale factor 3, so the rule of dilation is given by:

Using this rule, we get


Therefore, the coordinates of point A' are (21,12).
8(2)-y=4
16-y=4d
-1y/-1=-12/-1
y=12
(16,12)
The y-intercept is (0,-11), which is option C.
