PLEASE HELP ILL MARK BRAINLIST

the y- intercept is (0,1)

Step-by-step explanation:

because that is where the line falls on the y-axis

your welcome

have a great day!

Step-by-step explanation:

Y intercept is the point where the line intersect the y-axis

For this graph, notice it intersect at the first unit of y-axis, so it should be one.

- "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."
