△bcd is translated to become △b′c′d′ . △bcd has coordinates b(4, 2) , c(6, 2) , and d(6, 5) . △b′c′d′ has coordinates b′(2, 1) , c′(4, 1) , and d′(4, 4) . which answer describes the translation? vertical translation of 2 followed by a horizontal translation of 1 horizontal translation of −2 followed by a vertical translation of −1 vertical translation of 1 followed by a horizontal translation of 2 horizontal translation of −1 followed by a vertical translation of −2

- "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."

3/5

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.
