The slope of two lines are perpendicular only if their slopes multiplied together equal -1 (m1*m2 = -1). So if a line has a slope of -3 then a line perpendicular to this one has a slope of -1/-3 or 1/3.
The slope is the rise/over run of a line. The equation of a line is usually written in the form y=mx+b where m is the slope and b is the y-intercept. To find the slope, you can take two points on a line, find how much the line goes up (or down) between the two, and divide it by how much the lines moves to the right. Usually the slope is left in the simplest fraction form.
If two nonvertical lines are perpendicular, then the product of their slope is -1.An equivalent way of stating this relationship is to say that one line is perpendicular to another line if its slope is the negative reciprocal of the slope of the other. For example, if a line has slope 3, any line having slope - 1/3 is perpendicular to it. Similarly, if a line has slope - 4/5, any line having the slope 5/4 is perpendicular to it.
If two lines are parallel and one has a slope of 1.3, what is the slope of the other line?
The slope is rise over run. If another line was parallel, the slope would be the same.
