Answer:
Then the desired equation is y = -2x - 6.
Step-by-step explanation:
As we move from point (-3, 0) to point (0, -6), x increases by 3 and y decreases by 6. Thus, the slope of the line segment connecting these two points is m = rise / run = -6/3 = -2.
Now use the slope-intercept equation of a straight line to determine the y-intercept of this line:
y = mx + b becomes 0 = -2(-3) + b, so that b = -6.
Then the desired equation is y = -2x - 6.
Check: Does (0, -6) satisfy y = -2x - 6? Is -6 = -2(0) - 6 true? YES

Step-by-step explanation:
I'm pretty confident this would be correct, if not let me know and I will fix it. I'm sorry in advance if it is incorrect.
So 3 have no pets, so 25 - 3 = 22 students have a pet.
There are 15 cats and 16 dogs so 15 + 16 = 31.
And then 31 - 22 = 9. The 9 means that 9 students have both pets.
So the probability is 9/25.
