To find the slope you use the slope formula y2-y1 / x2-x1. So use two point on the line we will make ours (1,2) and (3,4). Substitute to make 4-2 / 3-1 = 1/1 so using the rise over run method. The line rises up one and runs by one. The slash mark means divide, it's easiest in a fraction.
Also if you come across the equation y=mx+b, m is the slope and b is the y-intercept, this is called slope intercept formula.
If you're trying to make an inequality, it would be:
30 - 4x > -10.
Answer:
Done below!
Step-by-step explanation:
(x - root)
(x - 2)(x - (-1))(x - (-5)) = (x - 2)(x + 1)(x + 5)

Im pretty sure its y= 5x-2
