The 2-point form of the equation of a line is
.. y = (y2 -y1)/(x2 -x1)*(x -x1) +y1
For your points (x1, y1) = (0, 3) and (x2, y2) = (3, 5), this is
.. y = (5 -3)/(3 -0)*(x -0) +3
.. y = (2/3)x +3
Written as a function, it is
.. f(x) = (2/3)x +3
Answer:
The percentage that the coat was reduced is 25%.
Step-by-step explanation:
A percentage is always out of a factor of 100.
40 x 2.5 = 100
30 x 2.5 = 75
75/100 = 3/4
1/4 is missing, which is the percentage.
1/4 = 0.25, or 25%

<span>3(a+(6x)y) was clearly multiplied out as seen by the 3a and 18xy, so the distributive property was used there. In addition, the commutative and associative properties state that you can rearrange sums, so those were used too </span><span />
