How do you find the slope intercept form of a equation?
To write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope.
This is the value of m in the equation.
Next, find the coordinates of the y-intercept–this should be of the form (0, b).
The y- coordinate is the value of b in the equation.
What is the slope intercept form?
The slope-intercept form of the equation of a line is y = mx + b, where m is the slope of the line, and b is the y-intercept. Since we are given two points, we can calculate the slope m as follows: Note that the slope is the same if we interchange the order of the points.
How do you find B in slope intercept form?
If you use the slope intercept form, y = mx + b, and know the slope, you can plug in any point of the line which will be a (x,y) value to find b. If you use the point slope form y-y1 = m(x-x1), you can put in any point and the math will work out the same.

What does M stand for in slope intercept form?
In the equation of a straight line (when the equation is written as “y = mx + b”), the slope is the number “m” that is multiplied on the x, and “b” is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named the “slope-intercept form”.
What is the point slope intercept formula?
You may already be familiar with the “y=mx+b” form (called the slope-intercept form of the equation of a line). It is the same equation, in a different form! The “b” value (called the y-intercept) is where the line crosses the y-axis.
How do you find the slope in a graph?
Using the Slope Equation
- Pick two points on the line and determine their coordinates.
- Determine the difference in y-coordinates of these two points (rise).
- Determine the difference in x-coordinates for these two points (run).
- Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).
