How many ways are there to partition a group of 16 people into: (a) a group of ten people, a group of four people, and a group of two people. (b) a group of ten people and two groups of three people. (this is a little tricky)?

Where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis. to write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. this is the value of m in the equation.
