The slope of a line is also called its gradient or rate of change. Text Slope dfrac goldD text Change in y greenD. Equation of Line Applet Point Slope Form of a Line.
Slope y₂ - y₁ x₂ - x₁ Notice that the slope of a line is easily calculated by hand using small whole number coordinates.
M2 m 2 we have a positive slope and therefore the straight line is rising or increasing from left to right. Sometimes you are not given two points to use in the formula. What does it stand for. Now we can write a general formula for slope.
