Question

Which of the equations below contains the two points listed? (-8,-3) and (-8,1) A. y=8 B. x=-8 C. x=8 D. y=-8

Answer 1

-8

Explanation:

i looked on plato got it right

Answer 2

Option B.

Explanation:

If a line passing through two points, then equation of line is

`y-y_1=(y_2-y_1)/(x_2-x_1)(x-x_1)`

It is given that the line passing through (-8,-3) and (-8,1). So, the equation of line is

`y-(-3)=(1-(-3))/(-8-(-8))(x-(-8))`

`y+3=(4)/(0)(x+8)`

The given line is a vertical line because slope
`=(4)/(0)=\infty`.

`0=4(x+8)`

`0=(x+8)`

`x=-8`

So, the equation of line is x=-8.

Therefore, the correct option is B.
