Question

does anyone knows how to find a slope?

Answer 1

cause i need to find a slope of the line between 4.3 and 8.8

Answer 2

To find the slope of a line, there could be different ways:

1) From the equation of the line of the form y = m x + c
here m = slope and c is the y-intercept
for this you got to reduce the equation in this form.

2) From any two points on the line or in the plane
say, the two points are (X1,Y1) and (X2,Y2) then the slope of the line segment joining these two points is equal to
m= (Y2-Y1)/(X2-X1)

Answer 3

okay but can you help me find the slope from the chart table? ^

Answer 4

it seems here you want to find the acceleration from this chart.
but the line segment joining these three points is not a straight line
it has a bend at 6.3sec

so the slope b/w 4.3sec and 6.3 sec is (6.8-3.4)/(6.3-4.3) = 1.6

and the slope b/w 6.3sec and 8.8 sec is (9.7-6.8)/(8.8-6.3) = 1.4

So, now it depend on what your question asks for..

Answer 5

Okay, the question is: Find the slope of the line between 4.3 and 8.8 seconds.

Answer 6

from the table, the graph plotted is a velocity-time graph. that said, velocity on y-axis and time on x-axis imply that slope = change in velocity / change in time.

change in velocity = 9.7 - 3.4 = 6.3
change in time = 8.8 -4.3 = 4.5

slope = 6.3/4.5 = 1.4

NB. A line is the distance between two points. A point is made of 2 coordinates. it would be impossible to just say you want the slope between 2 times... you'd need the corresponding velocities in order to find the slope

Answer 7

I haven't plotted this to find out if all 3 points form a straight line but yes there is the possibility that they do not from a straight line, hence if u need the slope between the first and last points in the table, then you consider the line connecting only those 2 points, unless it is a calculus question when you'd have to find the slope of the curve.
