Please help me! Do any one of them, as long as the answer is correct!

1.) Match each equation with the pair of points used to create the equation.

Column A Column B
1. y – 4 = -1(x + 4) a. {3, 3) and (-3, -3)
2. y – 3 = 1(x – 3) b. (0, 0) and (-4, 4)
3. y – 13 = 1(x + 2) c. (1, 3) and (-2.9, 3)
4. y – 3 = 0(x – 1) d. (-2, 13) and (0, 15)

2.) Enter an equation in point slope form for the line containing the points (5, 7) and (6, 3).

3.) Enter an equation in point slope form for the line.

Slope is -9 and (1, 2) is on the line.

4.) Enter an equation in point slope form for the line.

Slope is 1 and (1, 3) is on the line.

5.) Keisha is reading a 350 page book at a rate of 27 pages per day. Use a point-slope equation to determine how many pages she will have left to read after reading the book for 10 days.

How many pages will Keisha have left to read after 10 days?

6.) A rectangular swimming pool has a volume of 2,530 cubic feet. Water is being added to the pool at a rate of about 20 cubic feet per minute. Use an equation in point slope form to determine about how long will it take to fill the pool completely if there were already about 975 gallons of water in the pool. Use the fact that 1 cubic foot of space holds about 7.5 gallons of water. Round the answer to the nearest integer if necessary.

How many minutes will it take to fill the pool completely?

Answer:

1.) 1-b, 2-a, 3-d, 4-c

Step-by-step explanation:

You recognize that the point-slope form of the equation for a line with slope m and point (h, k) is ...

... y - k = m(x - h)

____

Match this form to the given equations to determine (h, k). Once you determine (h, k) from the equation, find that point in the list of points to get your match-up. (All the slopes are correct, so you don't need to do any more work than just described.)

_____

For problems 3.) and 4.), use the above form with the given point and slope.
