Question

Is the speed on this graph increasing or constant?

Answer 1

Answer:

The speed is constant.

Explanation:

The equation for a straight-line graph is  

y = mx + b

where m and b are constants.

m is the slope of the line and b is the y-intercept.

If we change the variables, the equation becomes

d = mt + b

$m = \frac{\Delta d}{\Delta t} = = \frac{\text{ distance}}{\text{time}} = \text{speed}$

Since m is constant, so is the speed.

Answer 2

i am pretty sure the answer to the prob is constant
