    Hi Tebeen Besarani,

    The slope of the line can be found by finding the tangent of the angle of inclination (the angle made by the line with the x-axis measured in a counterclockwise direction).

    So, find tan 45 degrees.

    This is a good site for beginning trigonometry students.

    There are special angles that you should memorize the six trigonometric function of by heart. You can't learn all the degrees. That wouldn't be practical (nor possible). You might also familiarize yourself with the unit circle. But, if you're just starting out, look at the tutorial I suggested.
