Parallel lines have the same slope. So if you know the slope of a line in question, or you can calculate it, then you know the slope of any line parallel to that line.

The slope of both lines will be the same.

the slope of a line = the Change in Y divided by the Change in X

To find the slope of a perpendicular line, take the negative reciprocal of the slope of the given line. (Flip the top and bottom of the fraction and change the sign.) The slope of 3 can be written as 3/1. The slope of a line that is perpendicular is -1/3.

Why do we need to find the slope of a line? The slope of a line tells us how something changes over time. If we find the slope we can find the rate of change over that period.Why do we need to find the slope of a line?The slope of a line tells us how something changes over time.

you look at the line and see if there are any direct points on the line the slope formula

If the slope of a line is m then the slope of an altitude to that line is -1/m.

To find the slope of a perpendicular line, take the negative reciprocal of the slope of the given line. (Flip the top and bottom of the fraction and change the sign.) The slope of a line that is perpendicular to a line with a slope of -2/3 is 3/2, (or 11/2 or 1.5).

Line a is parallel to line b, m, and . Find .

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 equation for the slope of a line is y=mx+b

An equation of a line requires two parameters. The slope, by itself, is not enough.

this is false Apex!

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.

If it is the equation for a line, then it can be rearranged into the format y = mx + b, where m is the slope of the line, and b is the point where the line intercepts the y-axis.If it is not for a straight line, then the slope is changing with x, and the derivative of the function would find the slope at a particular x.

Use the four-step process to find the slope of the tangent line to the graph of the given function at any point.

slope=rise over run

If you have any expression that defines a line, you can find the slope of the line. After you have found the slope of the line, you can then write an expression describing the line in slope intercept form. You can't define a slope-intercept form for any nonlinear equation, because the slope is always* changing; there are often several intercepts as well.

Slope of a line perpendicular to x-y=16

A line in slope-intercept form is: y = mx + b m is the slope of the line, and b is the y-intercept. To find the slope, find any two coordinates, and divide the difference in y-values by the difference in x-values; to find the y-intercept, find the value of y where x = 0.

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.

The slope can help you find the y intercept of a line, as well as many other coordinates.
