slope

SLOPE

y=mx+b

m=slope

HOW DO WE FIND SLOPE USING COORDINATE PAIR?

#1 ( 3, 3) #2 ( 5, 7)

Y₂ - Y₁

X2 - X₁

7-3 = 4 = 2 = 2

5-3 = 2 = 1

WHAT DO WE DO WITH THE ANSWER WE JUST GOT FOR SLOPE?

• Take it for ice cream

• substitute it into the slope intercept formula

• use it on a graph

• reciprocate it

SLOPE INTERCEPT FORMULA

We substitute the answer we got for m (slope) into the formula y=mx+b

We got 2 as our slope, so we substitute it for the m

y= 2x + b

y=mx+b

y=4x + b
