Since you already know that ordered pair is in the format of (x, y), then you can label one of the ordered pairs as 1 and kind of distribute it to get 1(x, y) = (x-sub1, y-sub1). Then just use the slope formula (y2-y1)/(x2-x1).

To find the slope of an equation given in y=mx+b, balance the equation until y is by itself without any constants. First subtract 8 from both sides to get 4y = 6x + 10. Next, divide the equation by the constant 4 to isolate y, giving you y = 3/2x + 5/2.

To find the slope of a feature, the horizontal distance (run) as well as the vertical distance (rise) between two points on a line parallel to the feature need to be determined. The slope is obtained by dividing the rise over run. Multiply this ratio by 100 to express slope as a percentage.

The larger the value of the gradient, the steeper the slope. The gradient of a straight line can be calculated by drawing a right-angled triangle between any two points lying on the line. If the line is sloping down then a negative sign is placed in front of the answer.

['If we write y=4 in the form of #y = mx+c, it will be:', 'y=0x+4.', 'The slope is therefore m=0.']

['Percent of slope is determined by dividing the amount of elevation change by the amount of horizontal distance covered (sometimes referred to as "the rise divided by the run"), and then multiplying the result by 100. ... ', '1,000 divided by 2,000 equals 0.5. ... ', '500 divided by 3,000 equals 0.166. ... ', '700 divided by 500 equals 1.4.']

['Find the derivative of the function. There are many different ways to do this, depending on the function.', 'Plug the x-value, x 1, of the point into the derivative. This is the slope of the function at the point.']

The slope equals the rise divided by the run: Slope =riserun Slope = rise run . You can determine the slope of a line from its graph by looking at the rise and run.

In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis).

The hypotenuse of the triangle (the diagonal) is the line you are interested in finding the slope of. The two 'legs' of the triangle are the 'rise' and 'run' used in the slope formula. Slope = rise/run.

Calculating Slope Since slope is defined as the change in the variable on the y-axis divided by the change in the variable on the x-axis, the slope of the demand curve equals the change in price divided by the change in quantity. To calculate the slope of a demand curve, take two points on the curve.

To find the slope of a line given the equation of the line, first write it in slope-intercept form. Use inverse operations to solve for y so that it is written as y=mx+b. Then you can easily see the slope since it is the coefficient of the x variable, or the number in front of x.

['Slope = change in y over the change in x.', 'Slope = (y2 - y1)/(x2 - x1)', 'Slope = rise over run.', 'You can pick any two points on a line to calculate the slope.', 'You can double check your answer by trying different points on the line.', 'If the line is going up, from left to right, the slope is positive.']

Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1), or the change in the y values over the change in the x values.

Correct answer: Calculate the derivative of by using the derivative rules. The derivative function determines the slope at any point of the original function. With the given point , . Substitute this value to the derivative function to determine the slope at that point.

You can't find the slope of a line if only given one point. If you had a visual representation of the line such as a graph or a table you could find a second point and then use the formula for slope, y = (y2-y1) / (x2-x1).

To find the slope, we will need two points from the line. Pick two x's and solve for each corresponding y: If, say, x = 3, then y = ( 2/3 )(3) - 4 = 2 - 4 = -2. If, say, x = 9, then y = ( 2/3 )(9) - 4 = 6 - 4 = 2.
