Question

What is the equation of a line that contains the points (2, −2) and (0, −2)?

a) y = 0
b) x = −2
c) y = −2
d) x = 0

Answer 1

( C )

Explanation:

Both Points On Y Axis Are -2, So The Answer Is Y=-2.

Answer 2

The equation of the line is y=-2

Explanation:

the equation of a line that contains the points (2, −2) and (0, −2)

`slope =(y_2-y_1)/(x_2-x_1) =(-2+2)/(0-2) =0`

Slope m=0

Equation of a line is

`y-y_1=m(x-x_1)`

(2, −2) is (x1,y1) and m=0

`y+2=0(x-2)`

y+2=0

y=-2

The equation of the line is y=-2
