How do we find "m" and "b"? b is easy: just see where the line crosses the Y axis. b = 1 (value of y when x=0) Putting that into y = mx + b gets us: With that equation we can now ... ... choose any value for x and find the matching value for y. For example, when x is 1: y = 2×1 + 1 = 3. So when x=1 we have y=3.

The "General Form" of the equation of a straight line is: A or B can be zero, but not both at the same time. The General Form is not always the most useful form, and you may prefer to use: And we are done! (Note: m = 2 and b = −5/2) Why Use It?
Select the calculation parameters and write their value to determine the equation of a line by using this equation of a line calculator. Calculate Using the Following: Two Points One Point & Slope(m) Intercept (b) & Slope (m) Three Dimension Points
18 Ιαν 2024 · Slope intercept form reads y = mx + b, where m is the slope (steepness) of the line, and b is the y-intercept, i.e., the value at which the line intersects the vertical axis. For example, y = -2x + 3. Standard form reads Ax + By + C = 0, where A, B, C are integers. For example, 2x + y - 3 = 0.
4 Οκτ 2024 · To compute the standard form equation of the line passing through (x1, y1) and (x2, y2): Compute A = y2 - y1. Compute B = x1 - x2. Finally, compute C = y1 × (x2 - x1) - (y2 - y1) × x1. The standard form linear equation from two points is Ax + By + C = 0 with A, B, and C as above.
