AnswerWhen the mass of a material is plotted against volume, the slope of the line is the density of the material.

Slope is easy. Just remember rise over run or change in y over change in x.Pick two points on the line: (x1, y1) and (x2, y2)The slope of the line is (y2-y1)/(x2-x1)How to find the slope if you are given two points:The equation for the slope of a line is (y2-y1)/(x2-x1). For example, if you have the points (4,8) and (7,6), the slope is (6-8)/(7-4), which is (-2)/3, which is -2/3. You can switch the x's and y's in the equation and get the same result, so you can rewrite the equation as (y1-y2)/(x1-x2). Using the points (4,8) and (7,6), the slope is (8-6)/(4-7), which is (2)/(-3), which is also -2/3.If you end up with 0 on the bottom (such as 4/0), the slope is undefined (since the line goes straight up and down.)How to find slope if you are given the equation of a line in slope-intercept form:See the related question below, "How_do_you_find_the_slope_of_an_equation".How to find slope if you are given the equation of a line in point-slope form:See the related question below, "How_do_you_find_the_slope_of_an_equation".How to find the slope if you are given the equation of a line in standard form:See the related question below, "How_do_you_find_the_slope_of_an_equation".How to find slope if you are given the graph of a line:See the related question below, "How_do_you_find_slope_on_a_graph".How to find the slope of a parallel or perpendicular line:The slope of a line parallel to a line with at given slope is the same as the line with the given slope. For example, the slope of a line parallel to a line with a slope of 3/2 is 3/2, and the slope of a line parallel to a line with a slope of -5 is -5.The slope of a line perpendicular to a line with a given slope is the negative reciprocal of the slope if the given line. Flip the bottom and top of the fraction, and then change the sign. For example, the slope of a line perpendicular to a line with a slope of 5/4 is -4/5. The slope of a line perpendicular to a line with a slope of 5 is -1/5. The slope of a line perpendicular to a line with a slope of -3/2 is 2/3.

The slope is directly related to the speed.

Slope of a line = m slope of perpendicular line = -1/m

A line with slope of zero is horizontal. A line with no slope is vertical because slope is undefined on a vertical line.

the steepness of the line is the slope of the line which is the rate of change; the steeper the slope, the faster the rate of change

The line perpendicular to a line with a slope of 1/5 has a slope of -5.

the rate of change is related to the slope; the higher the slope, the higher the rate. If the line is vertical, that is infinite slope or infinite rate of change which is not possible

For two lines to be parallel they must have the same slope. A line parallel to a line with slope -2 would have a slope of -2.

The lines below are perpendicular. If the slope of the green line is -1, what is the slope of the red line?

if the slope of a line is 2/3, then the slope of a parallel line would be 2/3.

If the line has a slope of 2, then the perpendicular line has a slope of -1/2. The slope of a perpendicular line is the negative reciprocal. Another example would be if the slope of a line is -1/4, then the slope of the perpendicular is 4.

Parallel lines have the same slope. The slope of the second line is also 13.

The slope of a line is undefined if the line is vertical.

The slope of a line measures the steepness of the line.

No, the slope of a horizontal line is 0. The slope of a vertical line is undefined.

The slope of a line and of a line parallel to it is the same.

Yes.. See related link for an example.

The slope of a vertical line is undefined. Horizontal slope is 0.

The slope of a horizontal line is zero. That's because the slope measures how steep the line is, and a flat line is not steep at all and therefore has no slope.

The slope is rise over run. If another line was parallel, the slope would be the same.

The slope of a line doesn't change if you zoom in or out.

There is no slope defined for a vertical line.
