Descartes, a French philosopher and mathematician, invented the coordinate plane while looking at a _______ on his bedroom ceiling?
According to legend, he conceived the idea while lying in bed, watching a fly crawl across the tiled ceiling, and realized he could describe its position using two numbers representing its distance from two intersecting walls.
How do you know when an equation is in slope-intercept form?
The "y" is by itself
