*Linear Equations & Functions - 5-6 questions
Slope - the change along the y-axis/the change along the x-axis, or Rise over Run.
Slope-Intercept Form
y = mx + b
m is the slope and b is the y-intercept (the point of the line that crosses the y-axis)

x1 = x
61 = 6
(xm)n = xmn
(x2)3 = x2×3 = x6
x0 = 1
70 = 1
(xy)n = xnyn
(xy)3 = x3y3
x-1 = 𝒙

(x/y)n = xn/yn
(x/y)2 = x2 / y2
xmxn = xm+n
x2x3 = x2+3 = x5
x-n = 1/xn
x-3 = 1/x3
x6/x2 = x6-2 = x4
xm/n = 𝒏√𝒙𝒎
= ( 𝒏√𝒙)m
x2/3 = 𝟑√𝒙𝟐

Geometry
Pythagorean Theorem
Triangles
Rectangles
Area = lw
Perimeter = 2l+2w
Volume = lwh
Isosceles Triangle
two sides that are equal in
length and two equal
angles opposite those
sides
Sum of angles = 180⁰
