Question

Aunt lori is going to give jenna 2$ for swimming one lap. $3.50 if she swims 2 laps, 5$ if she swims 3 laps, $6.50 if she swims 4 laps,,,increasing by 1.5 each lap she swims

What is an equation for this using "m" for the money and "l" for the lap

Answer 1

m = 2 + 1.5i

Answer 2

j is totally wrong

the answer is:

m=1.5i+.5

this is because 1.5 is your slope and .5 is your y intercept
