Expert Solution
Step 1

“Since you have posted a question with multiple sub-parts, we will solve first three subparts for you. To get remaining sub-part solved please repost the complete question and
mention the sub-parts to be solved”.

The slope of the position-time graph shows the velocity. The expression of slope is given by,
