Line segment rs has endpoints r (-2, 4) and s (-4,-1).
line segment r"s" has endpoints r" (3.-3) and s" (5,2).
name the transformations that map line segment rs to line segment r"s".
o
rotation of 90 counterclockwise about the origin, followed by a translation (x, y) - (x + 2, y + 1)
reflection over the line y = x, followed by a translation (x, y) - (x + 1, y + 1)
rotation of 180° about the origin, followed by a translation (x, y) = (x+1, y + 1)
o
translation (x, y) - (x + 1, y + 1), followed by a rotation of 180 counterclockwise about the origin

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

step-by-step explanation:

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
