Answer: m is the slope, b is the y intercept (Choice A)
For example, y = 2x+7 has a slope of 2 and a y intercept of 7 because m = 2 and b = 7.
The slope tells us how to move from point to point along the line. The y intercept is the location where the graph crosses the vertical y axis. The y intercept always happens when x = 0.
