I think it is B, since x goes right 4.5 times and y goes up 3 times.
Since ur using 12 as p we solve it now.
3 - 12 over -4 = 6
Move the negative sign to the left (3 - (-12/4)
Simplify 12/4 to 3 ( 3 - (-3)
simplify brackets (3 + 3)
finally the answer is 6
Subtract x from both sides so the answer would be; Y=-x+r
The answer is A. here why. if we take the 45 times 5 you get the answer of how much she made all together for babysitting, if she only made 225 all together, you take 300-225=75. so the 75 represent the other she made by doing chores. you take 75 divide by 5 which is how many weeks it took it took you get 15 which how much she made each week by doing chores
