Question

Find the slope, if it exists.
x=-4
Thanks a lot.
And I will be done with work and reviewing.

Answer 1

No slope.

Answer 2

How did you come to that conclusion? That way I'll know how to work it out.
Thank you

Answer 3

Since the equationGlossaryequation A mathematical statement that says two expressions have the same value; any number sentence with an = . is a verticalGlossaryvertical Perpendicular to horizontal; up and down as opposed to left and right. line, it does not cross the y-axisGlossaryy-axis The vertical axis in a Cartesian coordinate system. .

No Y-Intercept

Answer 4

Smacking self on the forehead. Thank you

Answer 5

Basically it does not cross the axis, so no Y intercept

Answer 6

it doesn't have to cross the y intercept to have a slope

Answer 7

what about piecewise functions?

Answer 8

the function doesn't have to be defined at x=0

Answer 9

x=a constant is a vertical line since slope=rise/run and there is no run then the slope is undefined
