I dont really know but do you have to pick one of the numbers from the score board or no i dont really know what grade your in so idk .-. sorry if i cant help
Slope-intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept.
For the equation y = 5x - 6, m = 5, meaning that the slope of the line is 5.
