Question

The two tables below show the amount of tip, y, included on a bill charging x dollars.Restaurant Aх102030y123Restaurant BXу25550107515Which compares the slopes of the lines created by the tables?O The slope of the line for Restaurant B is 5 times greater than the slope of the line for Restaurant A.O The slope of the line for Restaurant B is 2 times greater than the slope of the line for Restaurant A.O The slope of the line for Restaurant B is 5 times greater than the slope of the line for Restaurant A.O The slope of the line for Restaurant B is 10 times greater than the slope of the line for Restaurant A.

Answer 1

Given the values for x and y

The slope for restaurant A

m = (3 - 1)/(30 - 10)

=2/20

= 0.1

The slope for restaurant B

m2 = (15 - 5)/(75 - 25)

= 10/50

= 0.2

Hence the slope of the line for Restaurant B is 2 times greater than the slope of the line for Restaurant A.

Option B
