Answer:
y = -x -2
Step-by-step explanation:
The line crosses the y-axis at y = -2, so that is the y-intercept.
The slope is the ratio of "rise" to "run." The points on the graph show a "rise" of -3 for a "run" of 3.
m = rise/run = -3/3 = -1
Then the slope-intercept equation is ...
y = mx +b . . . . . slope m, y-intercept b
y = -x -2 . . . . . . . using m=-1, b=-2
Answer: Se colocará 220 peces en cada pecera pero necesitaremos 1 pecera más para colocar los 7 peces restantes.
Step-by-step explanation:
4627/21=220.33....

Hope this helped☺☺
