Absorbs harmful radiation from the sun
Answer:
The speed is constant.
Explanation:
The equation for a straight-line graph is
<em>y</em> = m<em>x</em> + b
where m and b are constants.
m is the <em>slope</em> of the line and b is the <em>y-intercept.
</em>
If we change the variables, the equation becomes
<em>d</em> = m<em>t</em> + b

Since m is constant, so is the speed.
