This gives us the linear function. Since the slope of a horizontal line is 0 the general formula for the standard form equation y mx b becomes y 0x b y b. 3 5 left 35 right 35 and.
Finding the Slope of a Linear Equation.
We then write the slope as a fraction. So sub 0 in for y and you get. When the line is graphed m is the slope of the line and b is where the line crosses the y-axis or the y-intercept. Slope Formula Calculator Enter any Number into this free calculator.
