Question 7 of 10 What is the equation of the following line? Be sure to scroll down first to see all answer options. (0, 0) (10. -2)

Sagot :

Answer:

The equation of the line with the given points is:

[tex]y=-\frac{1}{5}x[/tex]

Explanation:

Given the coordinates (0, 0) and (10, -2)

The equation of a line is in the form:

y = mx + b

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

The slope from the given coordinates is:

[tex]\begin{gathered} m=\frac{-2-0}{10-0} \\ \\ =-\frac{2}{10}=-\frac{1}{5} \end{gathered}[/tex]

The equation is now in the form:

[tex]y=-\frac{1}{5}x+b[/tex]

Using the point (10, -2) to find b, replace x by 10 and y by -2 in the last equation

[tex]\begin{gathered} -2=-\frac{1}{5}(10)+b \\ \\ -2=-2_{_{_{_{_{_{_{_{}}}}}}}}+b \\ b=0 \end{gathered}[/tex]

Therefore, the equation of the line is:

[tex]y=-\frac{1}{5}x[/tex]
