;
To find:
1. The distance between the points
2. The midpoint of the line segment joining the points
3. The slope of the line containing the points
4. The interpretation of the slope
Answer to Problem 2RE
Explanation of Solution
Given:
The points
Formula used:
Distance formula:
Calculation:
1. Let and
2. Midpoint of the line segment joining the points A and B:
3. Slope of the line containing the points A and B is
4. The slope means for every horizontal movement of 3 units to the right, there will be vertical (down) movement of 4 units.

If the problem can be solved using precalculus, solve it. If the problem seems to require calculus, use a graphical or numerical approach to estimate the solution. STEP 1: Consider the figure in part (a). Since this region is simply a triangle, you may use precalculus methods to solve this part of the problem. First determine the height of the triangle and the length of the triangle's base. height 4 units units base 5 STEP 2: Compute the area of the triangle by employing a formula from precalculus, thus finding the area of the shaded region in part (a). 10 square units STEP 3: Consider the figure in part (b). Since this region is defined by a complicated curve, the problem seems to require calculus. Find an approximation of the shaded region by using a graphical approach.
