Recall : • A Tangent Line is a line which locally touches a curve at one and only one point. The slope-intercept formula for a line is y = mx + b, where m is the slope of the line and b is the y-intercept.

Explanation: The slope of the tangent line represents the rate of change of a function. ... We can define an object's instantaneous velocity at a single instant of time, t , where the instantaneous velocity at time t is the slope of the line that is tangent to the position-versus-time graph at time t .

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.

The slope equals the rise divided by the run: . You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it. So, you can choose any 2 points along the graph of the line to figure out the slope.

Slope is the inclination of a straight line: for example, in y=3x, the slope is three. A tangent, on the other side, is a straight line that only touches something (a circle, a function…) at a single point. In calculus, the slope of a function at a given point is the slope of the tangent line.

Calculating a Slope in Degrees The most complicated way to calculate slope is in degrees and it requires a bit of high-school math. The tangent of a given angle (in degrees) is equal to the rise divided by the run. Therefore, the inverse-tangent of the rise divided by the run will give the angle.

Slope of a Line (Coordinate Geometry) Definition: The slope of a line is a number that measures its "steepness", usually denoted by the letter m. It is the change in y for a unit change in x along the line. ... The slope of a line (also called the gradient of a line) is a number that describes how "steep" it is.

The slope of a line can be thought of as 'rise over run. ' When the 'rise' is zero, then the line is horizontal, or flat, and the slope of the line is zero. Put simply, a zero slope is perfectly flat in the horizontal direction. The equation of a line with zero slope will not have an x in it.

Find Slope Using Tangent Draw a line tangent to the point using a ruler. Choose another point on the tangent and write its coordinates. Say, (6,7) is another point on the tangent line. Use the formula slope = (y2 - y1)/ (x2 - x1) to find the slope at point (2,3).

To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .

The derivative is the slope of a function at some point on the function. The limit is your best guess at where the function will eventually end up when it approaches a particular number. The slope of a function could be 0 and it could be approaching 2 at x=0 if the function is y=2, for example.

A horizontal tangent line is a mathematical feature on a graph, located where a function's derivative is zero. This is because, by definition, the derivative gives the slope of the tangent line. Horizontal lines have a slope of zero. Therefore, when the derivative is zero, the tangent line is horizontal.

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.
