Question
Let x = 0 represent the 1990. Find the year where the two types of restaurants was the same. Round to the nearest year as needed.
Year 1995 1999 2000 2001 2002 2003 2004
Full Service 95 118 129 135 140 145 153
Fast Food 104 111 117 121 124 126 132

Using the data points (0, 95) and (14, 153), we can find the linear regression equation for the "full service" restaurant.
First, let's calculate the slope:
slope = (change in y) / (change in x)
slope = (153 - 95) / (14 - 0)
slope = 58 / 14
slope = 4.143
Next, let's calculate the y-intercept using one of the data points:
y = mx + b
95 = 4.143(0) + b
b = 95
Therefore, the linear regression equation for the "full service" restaurant is:
y = 4.143x + 95
First, let's calculate the slope:
slope = (change in y) / (change in x)
slope = (153 - 95) / (14 - 0)
slope = 58 / 14
slope = 4.143
Next, let's calculate the y-intercept using one of the data points:
y = mx + b
95 = 4.143(0) + b
b = 95
Therefore, the linear regression equation for the "full service" restaurant is:
y = 4.143x + 95
