Answer: First Option
Walter needs to make at least 5 more cookies but no more than 40
Step-by-step explanation:
If we call x the number of cookies that Walter needs to make, then we know that the amount of cookies will be:
Then this amount must be greater than or equal to 20 and must be less than or equal to 55 then.
and
This is:
We solve the inequality for x.
Then the amount of cookies that Walter must make must be greater than or equal to 5 and less than or equal to 40
Slope (m) = 1/4
slope-intercept format is: y = mx + b
point-slope format is: y-k = m (x-h), where the point is at (h, k)
So we plug in for that using the point (8, 3):
y-3 = 1/4(x-8)
y-3 = 1/4x - 2 --> solve for y:
y-3+3 = 1/4x -2 +3
y = 1/4x + 1 --> now it's in slope-intercept format where the b is the y-intercept, which is +1
