Find the slope of the line with points (-1,-2) (2,7)

Mathematics
1 answer:
aleksandrvk [35]3 years ago
4 0

Answer:

3

Step-by-step explanation:

You may use this formula to find the slope of a line going through points (x_1,y_1) \text{ and } (x_2,y_2):

\frac{y_2-y_1}{x_2-x_1}

Notice the numerator is just a subtraction of the y's while the denominator is a subtraction of the x's. The order you choose your y's on top will matter to how you subtract the x's.

You could just line up the points and remember that the y difference goes on top and the x difference goes on bottom.

This is my favorite way.

(-1  ,   -2)

minus

(2  ,     7)

---------

-3      -9

The slope is -9/-3 or 3.

You could do it the other way:

(2   ,    7)

minus

(-1   ,    -2)

--------------

3           9

The slope is 9/3 or 3.

What is the missing number in the series?<br><br> 1, 16, 81, __, 625, 1296
Alinara [238K]

Answer:

256

Step-by-step explanation:

We are given the series

1, 16, 81, __, 625, 1296

The missing number in the sequence is the fourth term

From the above sequence, we know that

1, 4², 9² , __, 25² , 36²

Difference between first term = 4 - 1 = 3

9 - 4 = 5

x - 9 = 7

x = 9 + 7 = 16

Hence, the fourth term = 16²

= 256
