Then slope of a line formula is given as m tan th. Simplify the fraction to get the slope of -25. Equation from 2 points using Slope Intercept Form.
How to find slope.
Remember that slope is defined as riserun. To solve the problems in this lesson students use the slope formula which states that m y2 - y1 x2 - x1. We have that x 1 1 y 1 5 x 2 3 y 2 7. We get the same answer as before.
