Area of a Triangle

1/2 A TIMES B TIMES SINE THETA


If the equation of a line is given as Y=MX+B the slope is___ and the yIntercept is___

M and B


If the equation of a line is given as Ax+By+C the slope is__ and the Y intercept is__

A/B and C/B


The slopes of parallel lines are__ and the slopes of perpendicular lines are__

The Same and Negative Inverse


Equation for a Circle

(xh)2 + (yk)2 = r2 where R is the radius of the circle and (h,k) is the center point


Equation for a Parabola

Ax2 + Bx + C = Y (if A is positive then the parabola opens up for X squared and right for Y squared)
X=AY2 + BY + C (if A is negative then the parabola opens down for x squared and left for Y squared) 

Equation for a hyperbola

X2/A2Y2/B2=1 or
Y2/A2X2/B2=1 There is an X2 and a Y2 term If it is X2Y2 then curves open right and left, if it is Y2X2 the curves open up and down 

Equation for an Ellipse

X2/A2+Y2/B2=1
A does not equal B There is an X2 and a Y2 Both have positive coefficients The horizontal axis is 2A The vertical axis is 2B 

If you have f(absolute value of X)

The left side disappears


if you have the absolute value of f(x)

then the whole graph is positive
