Answer:

y = 2x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2, thus

y = 2x + c ← is the partial equation of the line

To find c substitute (2, 1) into the partial equation

1 = 4 + c ⇒ c = 1 - 4 = - 3

y = 2x - 3 ← equation of line

Answer: No association

Step-by-step explanation:

There is absolutely no pattern going on. This means that the miles ran per week are not really affecting the standing heartbeat. Therefore, I'd say there is no association.

Erin runs laps each day on a track that is 4/8 miles long. This week, she ran 4 4/8 miles on the track. How many laps did she ru
Vikki [24]
First, we're going to convert the mixed number into a/n improper fraction.
(4 × 8 ) + 4 = 36/8

Now we're going to divide 36/8 by 4/8 since 4/8 = 1 lap.
36 / 4 = 9.

That is how we get our answer, 9 laps.

Our final answer is 9 laps.

Hope this helps!~
