When you subtract a negative you're just adding the number. So: (-5) - (-7) = -5 + 7 = 2 2 + 9 + (-14) 11 + (-14) When you add a negative number you simply subtract that number. So: 11 + (-14) = 11 - 14 = -3 So this entire equation simplifies to -3
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.
