I like point point form because it doesn't fail in the no slope case. The line through (a,b) and (c,d) is
(c-a)(y-b) = (d-b)(x-a)
Point slope form is almost the same,

1. (a,b)=(4,0),(c,d)=(-2,1)
y - 0 = (1 - 0)/(-2 - 4) (x - 4)
Answer: y = (-1/6)(x-4)
2.
y - -2 = (3 - -2)/(5 - -3) (x - -3)
Answer: y + 2 = (5/8) (x+3)
3.
y - 1 = (4 - 1)/(3 - -5) (x - -5)
Answer: y - 1 = (3/8) (x+5)
square root of 16 would be 4
4 x 4 = 16
<u>Product is basically a vocabulary word meaning multiply</u>. 1500 x 1700 gives you a huge number that is 2,550,000.
The solutions to q² - 125 = 0 are q = ±√125.
q = -5√5
q = 5√5
