What is the slope of the line on the graph? Enter your answer in the box. A coordinate grid that includes the line y equals negative two x. Points are plotted at begin ordered pair 3 comma negative six end ordered pair begin ordered pair 0 comma 0 end ordered pair and begin ordered pair negative 3 comma 6 end ordered pair.

Respuesta :

 The slope is -2.
Hope this helps!

we have

the equation of the line is [tex]y=-2x[/tex]

the points are

[tex]A(3,-6)\\B(0,0) \\C(-3,6)[/tex]

Method 1

we know that

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

In this problem we have a direct variation

The constant of proportionality k is equal to the slope of the line

[tex]k=-2[/tex]

so

[tex]m=-2[/tex]

therefore

the answer is

the slope of the line is equal to

[tex]m=-2[/tex]

Method 2

we know that

the formula to calculate the slope between two points is equal to

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

we have

[tex]A(3,-6)\\B(0,0)[/tex]

substitute in the formula

[tex]m=\frac{0+6}{0-3}[/tex]

[tex]m=\frac{6}{-3}[/tex]

[tex]m=-2[/tex]

therefore

the answer is

the slope of the line is equal to

[tex]m=-2[/tex]
