What is the equation of the trend line in the scatter plot?
Use the two yellow points to write the equation in slope-intercept form. Write any coefficients as integers, proper fractions, or improper fractions in simplest form.

 y = x - 1

Step-by-step explanation:

The yellow points are located at the points (1, 0) and (8, 7)

For a linear equation that pases trough the points (x1, y1) and (x2, y2), the slope is:

s = (y2 - y1)/(x2 - x1)

Then, for our equation, the slope is

s = (7-0)/(8-1) = 1

Then our linear equation is

y = 1*x + b

where b is the y-axis intercept.

To find b, we can use that when x = 1, y = 0

0 = 1*1 + b

b = -1

Then our equation is y = x - 1

8496 cars

step-by-step explanation:

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
