Which graph represents the function y = x – 2?

Mathematics

svlad2 [7]3 years ago

Answer:

Create a point at (0, -2) and (5, 3) then draw a line that connects and extends beyond these two points.

Step-by-step explanation:

y = mx + b

m = slope which is rise over run

b = y intercept

y = x - 2 actually means y = 1x - 2

m = 1

b = -2

The y intercept of your graph is (0, -2) and your slope is 1 - so from the y intercept move up 1 (for the purpose of graphing move up 5) and to the right 1 (for the purpose of graphing move right 5) to the point (1, -1) or (5, 3) Just be sure to move up and to the right the same number of places and create a point. Then draw a line connecting and extending beyond these two points.

4. Compare/contrast the data sets below. Which data set has a range of 9, a mean of
VladimirAG [237]

Let's first find the mode of each data set.

Mode = the largest value - the smallest value.

A. 20 - 11 = 9

B. 31 - 5 = 26

C. 20 - 11 = 9

D. 15 - 6 = 9

B fails because its mode does not equal 9.

Let's find the mean of A, C, and D

The mean = the sum of all data values divided by the number of data values.

A. (11 + 11 + 13 + 15 + 20) / 5 = 14.2

C. (11 + 11 + 14 + 19 + 20) / 5 = 15

D. (6 + 10 + 14 + 15 + 15) / 5 = 12

Options A and D fail because their mean does not equal 15.

Let's find the median and mode of option C

Median = the value which falls into the middle of our data set

11, 11, 14, 19, 20 = 14

Mode = the value which appears most often

In option C, 11 appears twice and every other number appears once, therefore, 11 is the mode.

kati45 [8]
4 rows and 6 seashells in each row. 
Row 1: 0 0 0 0 0 0
Row 2: 0 0 0 0 0 0
Row 3: 0 0 0 0 0 0
Row 4: 0 0 0 0 0 0

You add all of them together 6+6+6+6=24 
Or you could do 6x4 and your answer would be 24
So the answer to the question is 24 seashells.
