Gradient of function formula

WebThe slope of a line in the plane containing the x and y axes is generally represented by the letter m, and is defined as the change in the y coordinate divided by the corresponding change in the x coordinate, between two distinct points on the line. This is described by the following equation: = = =.

Take the first point's coordinates and put them in the calculator as x₁ and y₁. Do the same with the second point, this time as x₂ and y₂. The calculator will automatically use the gradient formula and count it to be (11 - 1) / (3 - (-2)) = 2.

Subtract 12 from both sides of the equation to get 6x - 12 = 2y. You want to get y by itself on one side of the equation, so you need to divide both sides by 2 to get y = 3x - 6. This is slope intercept form, y = 3x - 6. Slope is the coefficient of x so in this case slope = 3.
