3x-4y=9
-3x+2y=9
the 3xs would cancel out. then you add the other numbers to get -2y=18. next you would solve for y. -2/18=-9 y=-9. next you would plug y back in to the equation to get -3x+2(-9)=9 next you would symplify to get -3x-18=9. then you would add 18 to 9 to get 27 -3x=27 next you would divide by -3 to get x=-9.
x=-9 and y=-9

Which transformation would take figure a to figure b​
Korolek [52]

Answer:

C. A reflection over the line y = -x

Step-by-step explanation:

You need to reflect that over a line that goes between the two of them. That imaginary line has a rise of -1 (it goes down 1 unit) and a run of 1 (it goes one unit to the right). In other words, the slope is -1. The line should also have a y-intercept of 0 it starts at (0,0).

Put that information in slope-intercept form

y = -1x + 0

You can take out the 0 because it adds nothing to the equation, and you can remove the one because of the same reason, but leave the negative sign.

y = -x
