Distance-Time Graphs Distance-time graphs are a way to visually
show a collection of data. They allow us to get a visual understanding of
speed. X-axis time Y-axis distance

Slope The proper equation
for a line is y=mx + b
The y is the dependant variable (on y -axis)The x is the independent variable (on x-axis)The m is the slope of the lineThe b is the y intercept of the line.

Slope in a distance-time graph In a distance-time graph the equation
changes from y= mx + b d = vt
d is the dependant variable, lying on the y axis.
t (time) is the independant variable and lies on the x axis.
v (speed) is the slope of the line. 0 (the initial distance) is the y intercept.

Slope and Speed In a distance time-graph, the slope
determines the speed. The steeper the slope, the greater the speed.
The object shown in graph A is travelling at a greater speed. It is covering a greater distance in a shorter time.

Finding speed from slope Slope (or v) is
equal to: y/Δx Δd/Δt Change in
distance/change in time

Rise over Run
Δd = d2 –d1
Δd = 7.7km - 1.9km Δd = 5.8km Δt = t2 – t1
Δt = 11.2min - 2.7min Δt = 8.5min v = Δd/Δt v = 5.8/8.5 v=0.68km/min
