Class be boring but anyways what is ( 2 x 2 − 1 )?

3

Step-by-step explanation:

In order to do this equation, your first step is to use the Order of Operations, or PEMDAS, which means that you multiply (M) two times two first before subtracting the equation (S). 2 times 2 is 4.  4 - 1 = 3. Hope I helped! :)

parallel lines have the same slope. so if the green line has a slope of -4, the slope of the red line is also -4.
