Answer:

Step-by-step explanation:
Distance covered by the train in crossing the pole = 100 m.






- Hence, the speed of the train is 72 km/h
Answer:
1,600,000
Step-by-step explanation:
Answer:
Pat a) The graph in the attached figure
Part b) 
The slope is 
The y-coordinate of the y-intercept is 
Step-by-step explanation:
Part a) Which line represents the linear equation
?
To graph the linear equation find the intercepts
we know that
The y-intercept is the value of y when the value of x is equal to zero
so
For x=0



The y-intercept is the point 
The x-intercept is the value of x when the value of y is equal to zero
so
For y=0



The x-intercept is the point 
Plot the intercepts to graph the linear equation
see the attached figure
Part b) Rewritten in slope-intercept form
we know that
The equation of the line into slope intercept form is equal to

where
m is the slope
b is the y-coordinate of the y-intercept
we have

convert to slope intercept form
isolate the variable y


The slope is 
The y-coordinate of the y-intercept is 
x1=1 and x2=9 Whenever you see x put the two answers there and it’s equal to 32.... I hope it helped???? :)
