Jane earns 12 dollars each hour working part-time at a bookstore. She earns one additional dollar for each book that she sells.
Let A be the amount (in dollars) that Jane earns in an hour if she sells B Books graph your equation
The equation that represents the amount Jane earns in an hour if she sells B books is:
A = 12 + B
To graph this equation, you can choose different values for B and calculate the corresponding values for A.
Let's choose some values for B:
B = 0
A = 12 + 0 = 12
B = 1
A = 12 + 1 = 13
B = 2
A = 12 + 2 = 14
B = 3
A = 12 + 3 = 15
Now you can plot these points (B, A) on a graph:
(B=0, A=12)
(B=1, A=13)
(B=2, A=14)
(B=3, A=15)
Connect these points with a line, and you will have a graph of the equation A = 12 + B. The line will have a slope of 1 and a y-intercept of 12.
