What is an equation of the line in point-slope form? How can the point-slope form be written in function notation?
harina [27]
The equation of a line in point slope form = y - y_1 = m(x - x_1)

To put y - y_1 = m(x - x_1) into function notation, we need to get y by its self.
Lets say we had a point (2,2) and a slope of 3. Ok, now that we have our point and slope, lets turn point slope form into  function notation.

y - y_1 = m(x - x_1)
y - 2 = 3(x - 2)
y - 2 = 3x - 6
y = 3x - 6 + 2
y = 3x - 8
Change the y to f(x)
f(x) = 3x - 8      <-----Function notation.

Use the properties you learned to show why (a+b)+c is equivalent to b+(a+c)
Vlad [161]
Using the Associative Property of addition, if you move the parentheses anywhere between a, b, and c, the answer will always be the same. Also, the Commutative Property of addition states that if you move the terms around, the answer is also still the same. So, (a+b)+c is the same as b+(a+c).

I really am confused on how to write a proof.
kvasek [131]

Since ABCD is a parallelogram, the opposite sides will be parallel and equal,

\begin{gathered} AB=CD \\ BC=AD \end{gathered}

Consider that AC acts as a transversal to the parallel lines AB and CD, so we can write,

\begin{gathered} \angle CAD=\angle ACB\text{ (Alternate Interior Angles)} \\ BC=AD\text{ (Opposite sides of parallelogram)} \\ \angle ADB=\angle CBD\text{ (Alternate Interior Angles)} \end{gathered}

So by the ASA criteria, the triangle AED is congruent to the triangle CEB,

Then the corresponding parts of the triangles will be equal,

\begin{gathered} AE=CE \\ BE=DE \end{gathered}

Hence Proved.
