How to divide decimals is easy it's exactly like multiplying decimals
when you have a point, it is a coordinate pair. in other words, it represents an x coordinate and a y coordinate that go together. it says, for (x,y), when you put x into your equation, the result will be y. thus, you can just put your point for the x and y values in the equation.
ex. (1,6)
when x = 1, y = 6
6 = m(1) + b

C!
parallel line: m1 x m2 = -1
-3 x 1/3 = -1
Replace the f(x) in the second equation will 6x + 5 so then it looks like 2(6x + 5) + 6. Then distribute so it’s 12x + 10 + 6 and then simplify to 12x + 16
