To find the slope m m m of a curve at a particular point, we differentiate the equation of the curve. If the given curve is y = f ( x ) , y=f(x), y=f(x), we evaluate d y d x \dfrac { dy }{ dx } dxdy​ or f ′ ( x ) f'(x) f′(x) and substitute the value of x x x to find the slope.

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. point on the line, denoted by (x1, y1), and the slope of the line, denoted by m, to calculate the slope-intercept formula for the line.

The point slope form of the equation of a line is given by y - y1 = m(x - x1). where (x1, y1) is a point on the line and m is the slope of the line.

The slope at any point on a position-versus-time graph is the instantaneous velocity at that point. It is found by drawing a straight line tangent to the curve at the point of interest and taking the slope of this straight line.

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. The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2.

Using two of the points on the line, you can find the slope of the line by finding the rise and the run. The vertical change between two points is called the rise, and the horizontal change is called the run. The slope equals the rise divided by the run: .

Step 1: Find the slope of the line. To find the slope of the given line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line 3x – 5y = 9 is m = 3/5. Therefore, the slope of the line parallel to this line would have to be m = 3/5.

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.

The slope of a quadratic function changes at each point along the function. It is found by taking the derivative of the function and evaluating the function at the point in question. f(x) = ax^2 + bx + c is the function and the derivative is f'(x) = 2ax + b.
