Select any two coordinates from the graph such as (7,4) and (9,7). The formula of slope is rise/run or y2-y1/x2-x1
(4-7/(7-9)=(-3)/(-2)= 1.5
The slope of the graph is 1.5!
Step-by-step explanation:
To solve the equation for s we've got to leave s alone

Answer:
<h2>2.5 hours</h2>
Step-by-step explanation:
Step one:
given data
for train one
speed= 50miles per hour
for train two
speed= 60miles per hour
the total distance between both trains=275miles
Step two:
the expression for speed= distance/time
so that, distance= speed*time
let the time be t
we are going to combine both distances
train one distance =50t
train two distance =60t
Hence total distance
50t+60t=275
110t=1=275
t=275/110
t=2.5 hours
<u>It will take 2.5 hours</u>
