A square pyramid has a base edge of 5.5 yards and a height
of 3.25 yards. What is the
volume of the pyramid to the
nearest tenth of a yard?

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.
