if someone could explain how to evaluate absolute value to me I would appreciate it and maybe you could explain how to solve the
MAVERICK [17]

When calculating absolute value (like those questions above) you do whatever is in the absolute value bars first (if its just a number then.... just make the number positive, even if it is negative or already positive) and whatever answer you get inside those absolute value bars will ALWAYS be positive unless it's like -[4} then it's a negative number bcz the positive outcome that comes out of the absolute value bars gets multiplied by -1 (or just turned negative). So, for the first one you do 22+48=70 and -7--20=13 and then make the outcome of both of those positive and then subtract them from each other 70-13=57. For the second one you do 7+-33=-26 and 4+16=20 and make the outcome of both of those positive and then you add 26+20=46 and so and so on for the other problems.

Bingel [31]

Answer:

-3

y = mx + b

m is the slope and to figure it out use below formula

m = (y₂ - y₁) / (x₂ - x₁)

  = (1 - 4) / (1 - 0)

  = -3 / 1
