Find the slope of the line passing through the points (2, 7) and (-1, 4). 3 1 -1

Answers

Answer:

Step-by-step explanation:

To find the slope of a line passing through two points, we can use the formula:

slope = (change in y) / (change in x)

Let's apply this formula to the given points (2, 7) and (-1, 4):

1. Determine the change in y:

change in y = 4 - 7 = -3

2. Determine the change in x:

change in x = -1 - 2 = -3

3. Calculate the slope using the formula:

slope = (-3) / (-3) = 1

Therefore, the slope of the line passing through the points (2, 7) and (-1, 4) is 1.

In summary, the slope of the line passing through the given points is 1.

Find the greatest common factor of 14, 20, and 25.

Answers

14=2                       20=2                            25=5
 7=7                        10=2                              5=5  
 1=1                         5=5                               1=1        
so the one for 14     1=1                                so the answer for 25
would be 2*7           so the answer for 20      would be 5*5
                                would be 2*2*5 or 4*5
