Answer: 1 1/2 yards of yarn
Step-by-step explanation: For this problem, we will simply be multiply 1/2 yard by 3 to get the amount of yard that Ahlam will need.
1/2 x 3/1 = 3/2 or 1 1/2 yards of yarn. Basically you multiply the top of the fractions first (1 x 3) = 3 Then, you multiply the bottom of the fractions second (2 x 1) = 2 (3/2 or 1 1/2)
Answer:
B. Yes, Every 3 days, sales increase by $1000
Step-by-step explanation:
A proportional relationship exists because the line cuts across the point of origin, (0, 0).
Constant rate of change is that there is an equal sales increase of $1,000 on every 3 days. Thus, on day 3, sales was $1,000. On day 6, sales was $2,000.
This shows proportional increase of $1,000 of sales, every 3 days.

Equation for line: y=mx+b where m is the slope and b is the y-intercept
We have the slope. We just need to find the y-intercept. Plug in the point and the slope and solve for b.
y=mx+b
1=4(-5)+b
b=21
Answer: y=4x+21
