Algebra 20 - Slope-Intercept Form

The lecture introduces linear functions whose graphs pass through the origin, represented by the equation Y = MX, where M is the slope. It then discusses affine functions, which do not pass through the origin, and how adding a constant B shifts the graph vertically, affecting the Y intercept. The concept of translation is introduced, and the slope-intercept form Y = MX + B is explained, showing how M and B determine the line's orientation and position on the Cartesian plane.

In the context of linear functions, what does it mean for a graph to be translated vertically?

What is the slope-intercept form of a linear equation and what do the constants M and B represent?

How does the value of B affect the vertical position of a line in the Cartesian plane?
