Yup. the x axis is the base and the y axis is the height, so it’s right.
Basically Samantha makes six bracelets per hour, so:
After 1 hour she makes 6
After 2 hours she makes 12
After 3 hours she makes 18
After 4 hours she makes 24, therefor the answer is B
This can also be modelled by the equation B = 6t, where B is the number of bracelets and t is the number of hours, so:
B = 6(4) = 24
I'd say the answer would be 8.
Line point L would be the midpoint of question 3.
