In math, the slope describes how steep a directly line is. It is sometimes dubbed the gradient.

You are watching: Y1-y2=m(x1-x2)

Equations for SlopeThe steep is defined as the "change in y" end the "change in x" of a line. If girlfriend pick two points on a heat --- (x1,y1) and (x2,y2) --- you have the right to calculate the slope by separating y2 - y1 over x2 - x1.Here space the formulas supplied to discover the steep of a line:  This line goes through the clues (0,0) and (3,3).Slope = (y2 - y1)/(x2 - x1)= (3 - 0)/(3 - 0)= 3/3= 1This line has a steep of 1. Shot using various points ~ above the line. Friend should acquire the same slope nevertheless of what points friend use. You deserve to see that the line has the clues (-2,4) and (2, -2).Slope = (y2 - y1)/(x2 - x1)= (-2 - 4))/(2 - (-2))= -6/4= - 3/2Special CasesSome special cases include horizontal and vertical lines.A horizontal heat is flat. The adjust in y is 0, so the slope is 0.A upright line has a readjust in x of 0. Because you can"t division by 0, a upright line has actually an unknown slope.Up or down - optimistic or an unfavorable SlopeIf girlfriend look in ~ the heat from left to right, a line the is moving up will have a positive slope and a line the is relocating down will have a an adverse slope. You can see this ~ above the two example difficulties above.
Rise end RunAnother method to remember how the slope functions is "rise over run". You can draw a appropriate triangle using any type of two point out on the line. The climb is the distance that the line travels up or down. The run is the distance that the line travels native left come right.
