y = 3x
y = −3x
y equals start fraction one over three end fraction x
y equals negative start fraction one over three end fraction x
question 2 (multiple choice worth 5 points)
(04.03 mc)
what is the slope of the line joining (10, 9) and (40, 3)?
−5
−4
negative start fraction one over five end fraction
start fraction one over five end fraction

(1) Required function is   . (2) Slope of line is .

Step-by-step explanation:

1)

The function passing through (-3,9), (-1,3), (0,0) and (3,-9).

From these points it is noticed that the value of function decrease by 6 if the value of x increases by 2 and y-intercept is (0,0).

Slope intercept of a line is

Where, m is slope and b is y-intercept.

So, function is defined as

The required function is   .

2)

It is given that the line joining two points (10, 9) and (40, 3).

Slope of line is

Therefore slope of line is .
