Question

Slope of 0, through the point (9,-7)

Answer 1

Use \(y-y_{1}=m(x-x_{1})\) where \(m=slope\)

Answer 2

only vertical line has a slope of zero, a vertical line can be y=3

where the points on the line can have any x value but the y value will be always 3

(anything, 3 )


Which vertical line has a point (9,-7) ? (think, the y is supposed to be equal to -7 (always) ).

Answer 3

Err, you mean horizontal line.

Answer 4

Yeah, tnx for correcting me :)
