Figure abcd is a rhombus with point a (3,-1) what rule would rotate the figure 270 counterclockwise

where (a,b) represents the coordinates for the pre-image and (-b,a) represents the coordinates for image.

Step-by-step explanation:

After rotating a figure  270° counterclockwise, then the x-coordinate interchanges with negative value of y-coordinate and y-coordinate interchanges with the value of -x coordinate.

The rule for rotating the figure 270° counterclockwise is given by :-

where (a,b) represents the coordinates for the pre-image and (-b,a) represents the coordinates for image.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
