What is the equation of this line in slope-intercept form?

Anna11 [10]

Answer:

Step-by-step explanation:

From the graph, you see the line intersects the y-axis at y = 2, so the y-intercept is b = 2.

Now we need the slope. We need to find the number of vertical and horizontal units to go from one point to the other. Starting at point (-1, 5), go down 6 units and then go right 2 units. The change in y is -6. The change in x is 2. slope = m = (change in y)/(change in x) = -6/2 = -3.

m = -3; b = 2

y = mx + b

y = -3x + 2

neonofarm [45]

Answer:

0.28

Step-by-step explanation:

Refer the attached figure

Given :

People who live in their hometown and graduated from the college =8

People who do not live in their hometown and graduated from the college = 10

People who did not graduate from college and lives in home town = 6

People who did not graduate from college and do not live in home town = 4

To Find : Among people who do not live in their hometown, what is the relative frequency of not graduating from college?

Solution :

The total no. of people who do not live in home town whether they are graduated or not graduated = 14

People who did not graduate from college and do not live in home town = 4

Thus Among people who do not live in their hometown the relative frequency of not graduating from college :

People who did not graduate from college and do not live in home town/total no. of people who do not live in home town whether they are graduated or not graduated

⇒ $\frac{4}{14}$
