We have that x 1 1 y 1 5 x 2 3 y 2 7. Use the two points to find the slope of the equation. Now all thats left to find is the.
Then y-intercept of a line by enters the value of x y slope m in the slope equation.
To find the slope you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points. This method covers problems that only tell you two points on a straight. To calculate Slope Intercept Form you need input two points x1 y1 and x2 y2. Substitute either point into the equation.
