write an equation in slope intercept form given two points Given two points on a line we can write an equation for that line by finding the slope between those points then solving for the y intercept in the slope intercept equation y mx b In this example we write an equation of the line that passes through the points
If you know two points on a line you can use them to write the equation of the line in slope intercept form The first step will be to use the points to find the slope of the line This will give you the value of m that you can plug into y mx b The second step will be to find the y Free slope intercept form calculator find the slope intercept form of a line given two points a function or the intercept step by step

How do I find the slope intercept line equation from two points To compute the equation of the line passing through points x1 y1 and x2 y2 Compute the slope as a y2 y1 x2 x1 Compute the intercept as b y1 a x1 The equation you need reads y a x b with a an b computed as above Writing equations from any two points Let s write the equation of the line that passes through 2 5 and 4 9 in slope intercept form Note that we are not given the y intercept of the line This makes things a little bit more difficult but we are not afraid of a challenge Finding m m Change in y Change in x 9 5 4 2 4 2 2
About Transcript Learn how to write an equation in slope intercept form y mx b for the line with a slope of 3 4 that goes through the point 0 8 We identify the slope m and y intercept b to create our equation y 3 4 x 8 Created by Sal Khan and Monterey Institute for Technology and Education Questions Tips Thanks Given two points left x 1 y 1 right x1 y1 and left x 2 y 2 right x2 y2 found in the line the slope is computed as The y y intercept b b is the point where the line crosses the y y axis Notice that in the graph below the red dot is always found on the main vertical axis of the Cartesian plane
