Answer:

y = - 2x + 7

Step-by-step explanation:

Note the differences in the corresponding values of y are constant

5 - 7 = 3 - 5 = 1 - 3 = - 1 - 1 = - 3 - )- 1) = - 2

This constant is the multiplier of the x values, thus

y = - 2x ± c where c is a constant

To find c substitute values of x into the equation

x = 0 → y = 0 ← require to add 7 to obtain corresponding value of y

x = 1 → y = - 2 ← require to add 7 to obtain corresponding value of y

Thus algebraic description is

y = - 2x + 7

Answer:

y = -2x + 7.

Step-by-step explanation:

The slope is (5-7)/1-0 = -2 ,

Checking with other values: slope = (- 3 - 7)/ (5-0) = -10/6 = -2.

So the function is -2x + c where c is some constant.

Plugging in the point (0, 7):

7 = -2(0) + c

c = 7.

So the answer is y = -2x + 7.

Answer:

The interquartile range is 50.

Step-by-step explanation:

To find our answer we have to first quartile 1 and quartile 3 are equal too. When we look at the plot quartile 1 is equal to 20, quartile 3 is equal to 70 because it is in between 60 and 80. Now to find the interquartile range we will subtract 70 from 20 and we get 50. Therefore, 50 is our answer.
