Linear Functions
Slope-intercept form
what is y=mx+b
The theorem can only be used with:
right triangles
Integers
What are rational
Solve for x.
72 = 8x
x=9
The coordinate plane has 4 of these
quadrants
Slope
They form the right angle.
Legs
A number that does not end or repeat.
Irrational
Solve for x.
6x - 8 = 40
x=8
The ordered pair; ( 0. -6) is located here
You plot this first when you have an equation in slope-intercept form.
"b" also known as the y-intercept.
Find the missing side when a leg is 16 ft and the hypotenuse is 20 ft.
12ft
Can be written in a/b form.
Rational numbers
Solve for x.
4(x +2) = 24
x =4
The origin has this ordered pair.
(0,0)
The slope for the equation x = 4
undefined

28 feet
Repeating decimals.
Rational
Solve for x.
12x -4 = 68
x = 6
The ordered pair; (-6, -19) can be located in this quadrant.
III
Every input has exactly one output.
Function
You can prove that you do NOT have a right triangle using the theorem; true or false?
True
