Complete the equation for the linear function whose graph contains the points
(9, 7) and (4, –8).

Step-by-step explanation:

The given points are

We can get the line equation passing through these points by applying point slope formula.

The slope of the line joining these two points would be,

The general point slope form of straight line is,

Putting the slope as 3 and the point as (9, 7),

c

step-by-step explanation:

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
