current skill\nwhat is the lines slope?

Explanation:

Step1: Select two points on the line

Let's take ((0,0)) and ((1,-4))

Step2: Use the slope formula (m=\frac{y_2 - y_1}{x_2 - x_1})

Here (x_1 = 0,y_1=0,x_2 = 1,y_2=-4) (m=\frac{-4 - 0}{1 - 0})

Step3: Simplify the expression

(m=\frac{-4}{1}=-4)

Answer:

(-4)
