The slope of the line below is -3. Use the coordinates of the labeled point to find a point-slope equation of the line. 10 -10 (5.-7) - 10+ O A. y-7 = 3(x + 5) B. y-73-3(x + 5) O C. y + 7 = 3(x - 5) D. y + 7 =-3(x-5)

y + 7 = -3 ( x - 5 )

Step-by-step explanation:

Point slope is:

We are given the slope of -3 and the point of (5, -7).

Replace the variables with the appropriate values.

The correct answer should be D.

Hope this helps.

- "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."

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.
