Note that in the case of a vertical line, the slope and the intercept are undefined because the line runs parallel to the y-axis. The line equation, in this case, becomes
Note that in the case of a horizontal line, the slope is zero and the intercept is equal to the y-coordinate of points because the line runs parallel to the x-axis. The line equation, in this case, becomes
Problem: Find the equation of a line in the slope-intercept form given points (-1, 1) and (2, 4) Solution: 1. Calculate the slope a: 2. Calculate the intercept busing coordinates of either point. Here we use the coordinates (-1, 1): 3. Write the final line equation (we omit the slope, because it equals one): And here is how you should enter this pr...
To use point-slope form, you need the slope and one point on the line. The point-slope form equation is: y – y 1 = m(x – x 1) The point-slope form equation states that y minus y 1 is equal to the slope of the line m times x minus x 1. In other words, the difference in y coordinates between two points is equal to the slope times the ...

Oct 3, 2024 · Calculation Formula. The Two Point Form equation is derived from the slope-intercept form of a line, \ (y = mx + b\), where \ (m\) is the slope and \ (b\) is the y-intercept. The formula for a line through two points \ ( (x_1, y_1)\) and \ ( (x_2, y_2)\) is: \ [ \frac {y - y_1} {y_2 - y_1} = \frac {x - x_1} {x_2 - x_1} \]
