(06.02 mc) the equation of line cd is y=3x-3. Write an equation of a line perpendicular to line cd in slope intercept form that
Fynjy0 [20]

Answer:

y = - \frac{1}{3} x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x - 3 ← is in slope- intercept form

with slope m = 3

Given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{3}, hence

y = - \frac{1}{3} x + c ← is the partial equation of the perpendicular line

To find c substitute (3, 1) into the partial equation

1 = - 1 + c ⇒ c = 1 + 1 = 2

y = - \frac{1}{3} x + 2 ← equation of perpendicular line

Plz help me will give brainlyest
Tom [10]

Answer:

1. x = independent variable: Age

y = dependent variable: Accidents

2. Age scale and Accidents scale

The scale for age ranges from 15 - 30 with the value of 5 difference between each number.

While the accidents scale ranges from 0 -1 with no difference in between.

3. In my opinion, the scatter plot looks as though it decreases in accidents once the age rises. As seen from the data shown.

Step-by-step explanation:

1) x is considered as  the independent variable, while y is considered the dependent value.

2) There are two sets of scales, one for the x and the other for y. These scales are the values that are interpreted in order to show data of the graph, due to their number and various size(s).

3) If you were to draw a line through the graph, you can somewhat create the image that the line would go down into the right corner! Meaning that it is decreasing over time.
