Question

- When writing an equation of a line given two points, which form should you

use if you do not know the y-intercept?


I don’t get can someone answer this?

Answer 1

Explanation:

If you want to write the equation of a line given only 2 points, you would first find the slope of both points using the slope formula, [(y2-y1)/(x2-x1)].

Then once you have your slope, you would use the point-slope formula to write your equation. (y-y1=m(x-x1)).
