Given the table for the linear function k, find the equation for the function.
Write in slope intercept form please

Given:

Table for the linear function k.

To find:

The equation for the function.

Solution:

Take any two points from the table.

Let the points are (10, 18) and (30, 58).

Slope of the line:

Here,

m = 2

Using point-slope formula:

Add 18 on both sides.

Replace x by c and y by k.

The slope-intercept form of the equation of the function is k = 2c - 2.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

the answer is 8/21

hope this
