Answer:
B, 6 miles per hour
Step-by-step explanation:
1. 4/3 of a mile in 4/18 of an hour, rewrite as (4/3 / 4/18)
2. Dividing fractions is multiplying by the reciprocal, so (4/3 * 18/4)
3. (4/3 * 18/4 = 72/12)
4. 72/12 can be simplified to 6/1 or 6.
5. Answer is B, 6 miles per hour
Answer:
y= 5x - 3
Step-by-step explanation:
For the slope, use this formula (y2 - y1) / (x2 - x1)
I used (1,2) and (2,7) from the chart
plug 7 for y2, and 2 for x2
then plug 2 for y1, and 1 for x1
7-2 / 2-1 = 5/1 = 5 <-- this is the slope.
Find the y intercept by plugging in (1,2) into y=5x + b
2 = 5(1) +b
2= 5 + b (subtract 5 on both sides)
-3 = b
So the answer is y= 5x - 3
