I'll solve B, and then challenge you to do A and C on your own!

If the line passes through (-3,4) and (5, -4), then the slope is the change in y over the change in x, which is (4-(-4))/(-3-5)=8/-8=-1 in this scenario, meaning that in the equation y=mx+b (with m as the slope), we have y=-x+b so far.Note that we only have to find b, as y and x can stay as variables. Plugging (-3,4) in for y and x (to find B), we get 4=-(-3)+b=3+b. Subtracting 3 from both sides, we get b=1 and the equation being y=-x+1

HELP!!! 10 POINTS OFFERED!!THIS IS MY LAST QUESTION!!

Answer:

A (-2,8) B (-1,5) C (-6,2)

A(-2,-7) B(-5,-8) C(-8,-3)

Step-by-step explanation:

x,y x,y x,y

A(7,-2) , B(8,-5) , C(3,-8)

translation (7-9),(-2+10) (8-9),(-5+10) ( 3-9),(-8+10)

(x-9) and (y+10) (-2,8) (-1,5) (-6,2)

when rotation 270 degrees counterclockwise around the origin:

A(x,y ) Then A'(-y,x) means switch x and y and make x negative

A(7,-2 ) rotation 270 degrees counterclockwise (-2,-7)

B(8,-5) to (-5,-8)

C(3,-8) to (-8,-3)
