What is the slope of a line that is perpendicular to the line y= 1/3 x - 2

drek231 [11]

Answer:

slope = - 3

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 = $\frac{1}{3}$ x - 2 ← is in slope- intercept form

with slope m = $\frac{1}{3}$

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

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{\frac{1}{3} }$ = - 3

Adam’s car traveled 465.3 miles on 16.5 gallons of gas. Which equation can be used to determine the average number of miles that

Nostrana [21]

Answer:

$y=28.5x$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form $y/x=k$ or $y=kx$

In this problem

Let

x------> the number of gallons

y------> the number of miles

the relationship between the number of miles and the gallons of gas represent a linear direct variation

The constant of proportionality k is equal to the slope m

$m=\frac{465.3}{16.5}= 28.2\frac{miles}{gallon}$

therefore

the equation of the linear equation

$y=28.5x$

Which diagram shows the medians of a triangle?

aalyn [17]

For this case we have that, by definition, the medians of a triangle are the line segments that are drawn from a vertex to the midpoint of the opposite side of the vertex. The medians of a triangle are concurrent at a point.

If we look at the figure, we can discard triangles 3 and 4.

Also, by definition, the median divides the vertex angle into two equal angles.

Thus, the correct option is triangle 1.

Answer:

Triangle 1
