Question 50749: How do you find the slope and intersept of a graph?
Answer by checkley71(8403)   (Show Source):
You can put this solution on YOUR website! THE SLOPE OF A LINE IS FOUND BY IDENTIFYING TWO POINTS (X1,Y1)(X2,Y2) THEN YOU CALCULATE THE SLOPE THUS (Y2-Y1)/(X2-X1)
EXAMPLE (3,5)(5,8) GIVES A SLOPE OF (8-5)/(5-3) OR 3/2 OR 1.5
TO FIND THE Y INTERCEPT LOOK FOR THE PLACE WHERE THE LINE INTERCEPTS THE Y AXIS.
THEN YOU USE THE FORMULA FOR A LINE (Y=mX+b) WHERE m=slope & b=Y INTERCEPT.
