How to Find Slope and Y Intercept With Coordinates

Y mx b or sometimes y mx c m slope the amount of rise over run of the line b y-axis intercept where the line crosses over the y-axis To calculate the slope intercept form equation from two coordinates x 1y 1 and x 2y 2. Find y-intercept y mx b 1 3 1 2 b 3 5 b substitute 2 1 for x and y Slope-intercept form y 3 1 x 3 5 Standard form x 3y 5 Recall that the standard form of the equation of a line is Ax By C.

Find the slope using the slope formula.

. You have the equation of a line 6x - 2y 12 and you need to find the slope. If you have the equation for a line you can put it into slope intercept form. Ok now lets apply this skill to solve real world problems.

Write the equation using the slope and y-intercept. If B0 the slope and y-intercept can be found by changing the equation to slope-intercept form. The coefficient of x will be the slope.

Slope Intercept Form Equation. Find the y-intercept by substituting the slope and the coordinates of 1 point into the slope intercept formula y mx b. Ax By C By.

Find Slope From an Equation. Slope intercept form y 7x - 9 becomes 7x - y 9 written in standard form. Calculate the slope y 2 - y 1 x 2 - x 1.
