The slope-intercept form is simply the way of writing the equation of a line so that the slope (steepness) and y-intercept (where the line crosses the vertical y-axis) are immediately apparent. Often, this form is called y = mx + b form.
Time = distance/speed So all you have to do is plug the numbers in and you get the answer Time = 1,250 kilometres/150 kilometres per hour Time = 8.333 hours
