Answer:

Step-by-step explanation:
The coordinates of the given quadrilaterals are

The reflection in the line
has the mapping,

We just have to swap the coordinates.
This implies that,




Therefore the correct answer is A.

M= (y2-y1)/(x2-x1)
Plug in the points. (2,3) (9,7)
m= (7-3)/(9-2)
m= 4/7
Slope= 4/7
I hope this helps!

Answer:
sin90 =1
cos 90 = 0
Step-by-step explanation:
θ = 90 degrees
Answer:
The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.
