Math 101

Standard Form

AX+BY=C

Find An Equation

Always use Point Slope Form

Find An Equation

End result should be an equation that is in Slope Inercept Form

Horizontal Line

Has a slope of zero

Vertical Line

Has a slope that is undefined

Slope Form

M=Y2-Y1 X2-X1 Only use when you have 2 coordinates

Parallel Line

Same Slope, Different Y-Intercept

Perpendicular LIne

Slope is negative reciprocal Always change the sign and the order

Point Slope Form

Y-Y1=M(X-X1) End result should be in Slope Intercept Form

Slope Intercept Form

Y=MX+B Always solve for y
