Question

Write an equation of the line that passes through(0,4)and(0,-3)

Answer 1

`\bf (\stackrel{x_1}{0}~,~\stackrel{y_1}{4})\qquad (\stackrel{x_2}{0}~,~\stackrel{y_2}{-3}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-3-4}{0-0}\implies \cfrac{-7}{0}\impliedby und efined`

when the slope of the points is undefined, is a flag that is a vertical line.

Check the picture below.

Answer 2

Hi there! :)

Explanation:

`Slope=(Y_2-Y_1)/(X_2-X_1)=(RISE)/(RUN)`

`((-3)-4)/(0-0)=(-7)/(0)=0`

Therefore, the slope is 0.

Undefined.

Final answer is 0.

I hope this helps you!

Have a nice day! :)
