4/7 of the bag is red marbles, which can be written as 4:7
Answer:
m = -3
y-intercept = 5
Step-by-step explanation:
You can use the rise/run approach on this graph. You start at the first point, which luckily, is the y-intercept (0, 5).

You can count 3 units down (which gives you the -3) and then 1 unit right (which gives you the 1).
You can now reduce the fraction to -3.
