What is the slope and y-intercept in the equation y = 5x - 7?

The slope would be -7 and the y-intercept would be 5

Substitute the x for a 0

5✖️0= 0

This leaves you with

Y=0-7

Remove the 0 since you subtract

Y= -7

Slope= 5

Hope this helps! :3

C) The mean is the same for both classes.

Step-by-step explanation:

We have been given the top ten scores on a quiz in two classes. We are asked to choose the correct statement about the given data.

Class A: 100, 100, 100, 90, 95, 85, 92, 98, 92, 88

Class B: 100, 100, 98, 95, 95, 96, 95, 92, 81, 88

Let us see our given choices one by one.

A) The mode is the same for both classes.

We can see that mode for class A is 100 and mode for class B is 95. Since mode for both classes is different, therefore, statement A is false.

B) The range is the same for both classes.

Since range for both classes is different, therefore, statement B is false as well.

C) The mean is the same for both classes.

Since mean for both classes is same, therefore, statement C is true.

D) The median is the same for both classes.

Let us arrange both data sets in ascending order.

Class A: 85, 88, 90, 92, 92, 95, 98, 100, 100, 100.

Class B:  81, 88, 92, 95, 95, 95, 98, 96, 100, 100.

Since the median for both classes is different, therefore, statement D is false.
