//Question number 1//
When graphing an inequality there are certain things to keep in mind that make it different from an equation of a line.
Here are some of them:
*You must look out to see whether it will be dashed or solid
*You must know which side of the graph to shade it in
*If they are not in standard form, you have to change them into standard form (THIS ONE MIGHT ACTUALLY APPLY TO A REGULAR EQUATION)
----Basically, the main difference is that in a "normal equation" you have an equal sign while in an inequality you have inequality signs (≤, ≥, <, >)----
//Question Number 2//
------ When using ≤ or ≥ (where they have half the equal sign at the bottom) the line for the inequality would be solid
------ When using < or > (where there is no equal sign- just the inequality sign) the line for the inequality would be dashed

The average speed is the ratio between the distance covered, and the time elapsed to cover that distance.
The total distance is the sum of the three distances covered:
Similarly, the total time elapsed is
So, althought you didn't always travelled with the same speed, you globally covered 170km in 1.75 hours. This leads to an average speed of
