SLOPE

 

Definition

m=y2-y1÷x2-x1 OR m= Δy , Δx

 

The slope(m) of a line through points (x,y) and (x2,y2)

Term

EQUATION OF A LINE= Y=MX+B

YOU NEED M AND B!


Definition

 

-to find b, plug the slope and one of the points in to y=mx+b. Equation of a line that passes through         (-3,1) and (2, -1)

y=-2/5m+b

 

Term

TO SOLVE FOR Y

EQUATION OF A LINE

Definition

write y=mx+b

m is a coefficient b is the constant

2x+3y=-8

3y+-2x-8

y=2x-8/3
