Answer:
y-4 = 3(x-1)
Step-by-step explanation:
First you will need to find the slope of the two points.
You can do this by using the slope formula:
Which would equal :
You would also have to know what point-slope form is:
Now insert your points, and the slope.
y-4=3(x-1)
The answer is (-4,9)
When you reflect across y=-x the x and y coordinates switch places and change signs.
The only way for you to get an answer is by doing $5.25x2=$10.5 and $3.50x3=$10.50
no you cant
