Terry is putting a fence around his circular pasture. the radius of the pasture is 25 ft. which of the following gives the best estimation of how much fence terry will need

It need to be at least 50 ft long and 50 ft wide.

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.
