Math 101
Slope Form Correct Answer: M=Y2-Y1
X2-X1
Only use when you have 2 coordinates
Point Slope Form Correct Answer: Y-Y1=M(X-X1)
End result should be in Slope Intercept Form
Slope Intercept Form Correct Answer: Y=MX+B
Always solve for y
Standard Form Correct Answer: AX+BY=C
Parallel Line Correct Answer: Same Slope, Different Y-Intercept
Perpendicular LIne Correct Answer: Slope is negative reciprocal
Always change the sign and the order
Horizontal Line Correct Answer: Has a slope of zero
Vertical Line Correct Answer: Has a slope that is undefined
Find An Equation Correct Answer: Always use Point Slope Form
Find An Equation Correct Answer: End result should be an equation that is in Slope Inercept Form
