The slope of a line on a distance-time graph represents
time
distance
speed
displacement

speed

Step-by-step explanation:

In a distance-time graph:

Distance is the y-variable (dependent)

Time is the x-variable (independent)

The slope of a line is rise/run, or can also be calculated with this equation, where "m" is slope:

slope = y-variables / x-variables

slope = distance / time

If you divide distance by the time it took to get that far, you will find how fast you got there. This is called the speed.

You might also see this formula:

k = d/t

In the options, "time" and "distance" would not make sense, because those are the variables on the x-axis and y-axis.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.
