Graph the equation y=-x. is (5,5) on the line? what is the slope of the line?
bezimeni [28]
You'll actually need to graph for the first segment
but the second part can be solved with algebra

The equation of the line is y(x)=-x

if we test the co0ordinates we can find if the point lies on the line

(5,5)
y(x)=-x

Using the x co-ordinate
y(5)= -5
y=-5

Leaving us with (5,-5)

Because (5,-5) is not (5,5)
This is not a point on the line

The slope of the line is -1

Someone help me plsh
Klio2033 [76]

Answer:

See attached image

Step-by-step explanation:

With this type of reflection, one has to convert the points of the form (x, y) into (y, x).

So the vertices of the triangle will transform the following way:

(4, 4)   into image (4, 4)

(4, 1)   into image  (1, 4)

(2, 1)  into image  (1, 2)

Please see attached picture to find the new reflected triangle depicted in red.
