Question 775434
Yes! Most definitely.

The {{{angle}}} the line makes with {{{x-axis}}} is given by arctan or  tan^-1  of the slope.

For example if the slope is {{{1}}} then the angle to the {{{x-axis}}} is {{{arctan (1) = 45}}} degrees

Size of the angle formed with the {{{x-axis}}} is related to the sign of the slope.
Lines with {{{positive}}}{{{ slopes}}} slant to the {{{right}}}, thus a {{{smaller}}} angle is formed with the {{{x-axis}}}.
Lines with {{{negative}}} {{{slopes}}} slant to the {{{left}}}, thus a {{{larger}}} angle is formed with the {{{x-axis}}}.


{{{y = 3x+5}}}  (Green Line)

{{{y = -3x+5}}}  (Blue Line)
