hey bro,
I have assume that you don't know the meaning of slope, so let us find out
slope: it is the change of something ( say y), with respect to some other thing ( say x). example: velocity is the rate of change of displacement with respect to time.
in the same way if we take this knowledge and relate it with the graphical representation.
we will get to know that the line ( say y) when is elevated from the origin to 45 degrees with respect to x axis, then slope is equal to the change in y divided by change in x. By using trigonometric ratios tanθ = change in y divided by change in x.
hence we can conclude that tanθ = slope.
in your case θ = 45 degrees.
therefore, slope = tan45
and slope = 1 ……………………………………………(tan45=1)
hope you are totally satisfied with this contempt answer.
this once is not for the person who asked question.
the writer takes a deep breathe in and …….. submits the answer.
