Slope intercept form is a way to write a linear equation so that the slope and the y intercept are immediately visible. The form is y = mx + b, where m is the slope and b is the...

math

The y intercept characteristics describe the point where a graph crosses the vertical y-axis, represented as the constant term in a linear equation such as y = mx + b. In this f...
