Through which angle of rotation does the image of a regular pentagon coincide with its preimage? a. 90° b. 72° c. 60° d. 45° e. 30°

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.
