## How to Write a Slope Intercept Equation From Looking at a Graph?

A graph's slope-intercept equation defines its functions in terms of two elements: the slope, which is also known as the gradient, and the line's intersection with the y-axis. The slope determines ...

## How to Write an Equation of a Line Given Y & X Intercepts?

Just as two points make the graph of a line possible, two points create the line's equation, which is also known as a linear equation. Two of important points of a line are its x- and y-intercepts,...
