Answer:

Step-by-step explanation:

Y-y1=m(x-x1)

Y- 3= 1/4(x- 8)

Y-3= 1/4x- 2

Y= 1/4x+1

Y intersept= 1

In an average of 65 minutes if a train stops at three stations for two minutes each and the distance is 115 miles between stops

larisa86 [58]

Answer:

117mph

Step-by-step explanation:

Given that

Total number of stations= 3

Total average time of journey of train = 65

total stop time at three stations = 3×2 =6 min

Total distance between stops = 115 miles

as we can see

Total time train was travelling = 65- 6 =59 min

so, average speed of train can be calculated as:

Average Speed = $\frac{Distance -travelled-between -stations}{Total-time-the-train-travelled}$

Average Speed = $\frac{115}{59} =1.95 miles/minute$

To convert this speed into miles per hour (mph) multiply the above speed by 60

Average speed = 60×1.95 =117 mph

So the average speed of train is 117mph.

Finding Slope On a coordinate plane, a line goes through points (0, 1) and (4, 2). What is the slope of the line? m =

ivolga24 [154]

Answer:

slope = $\frac{1}{4}$

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (0, 1) and (x₂, y₂ ) = (4, 2)

m = $\frac{2-1}{4-0}$ = $\frac{1}{4}$
