How to Write Linear Equations From Y-Intercept and A Slope
TL;DR: Think of a linear equation as a clean little description of a straight line. Once you know two things, the slope (call it m) and the y-intercept (call it b), you can write the whole line in slope-intercept form, y equals mx plus b, in a single move. The slope tells you how steep […]
How to Find x- and y-intercepts in the Standard Form of Equation?
In standard form Ax + By = C, the x-intercept comes from setting y = 0 and solving for x, and the y-intercept from setting x = 0 and solving for y. Below: the method step by step, worked examples, and the sign errors that most often flip an answer. Quick answer: For a line […]
