Joanne has 2a^3 number of animals. ronnie has 3a^3 number of animals . odessa has a^4 number of animals . how many animals do joanne , ronnie, and odessa have altogether?

They have:

2a^3 + 3a^3 + a^4
= 5a^3 + a^4

Answer is A. y=-6 is a horizontal line that runs through (0,-6). It has no slope because slope=rise/run ( As they teach in school, but the slope can be thought of as the hypotenuse of a triangle ).

Since there is no “rise” but is only “run”, such that slope=0/anything is 0. ¿Comprendes?
