Y = mx + b where m = slope and b = <span>y-intercept
</span><span>slope of -3 and a y-intercept of -4
so
y = -3x - 4
answer
</span><span>D. y = -3x - 4</span>
if i read the data correctly, the answer should be “spaghetti and pizza are preferred almost equally” because if you add the numbers for each sample for each of the foods, the numbers are almost equal.
Let's assume that Susan's graph is linear. Then, we can do linear interpolation. Let y be the amount charged for 10 hours of work done:
(7-10)/(7-11) = (168-y)/(168-264)
y = $240
For Jim's Lawn care, let's find the constant slope using points (1,20) and (2,40):
m = (20 - 40)/(1-2) = 20
Then, since the y-intercept is zero, the linear equation is:
y = 20x
Substituting x = 10 hours,
y = 20(10) = $200
The difference between the two would then be:
Difference = $240 - $200 = $40
Answer:
10 pounds of dog food.
Step-by-step explanation:
You can find this answer by multiplying 1/4 to 40
Because
There is 40 small dogs and each eats 1/4 of dog food
