Answer:
The answer is B
Step-by-step explanation:
Triangle ABC was reflected across the y-axis and then translated 7 units down.
The point at which a line crosses the y-axis is called its y-intercept. It is generally in the form (0, y-int). To find this value, we can plug in 0 for x and then solve for y.
Steps:
y = 9(0)
y = 0
The point at which the graph of y = 9x crosses the y-axis is (0,0).
If there was a mistake somewhere, please do let me know! As I know that the answer I gave above is not on the list of answer choices. I would strongly recommend checking the equation in the original problem once more. :)
It means you multiply 3x by -4. You could also think of it as 3x multiplied by 4 and then adding the negative. You'd get -12x
Point B is located at (-6, 5)
Multiply each coordinate by the scale factor 3 to get
-6*3 = -18
5*3 = 15
The point B' is located at (-18, 15)
