algebra 2 slope: in 2003, y = $1.40; in 2004, y = $1.50.

[kerrielynn]

i need to find the slope of a line representing the change from 2003 to 2004 letting the year represent "x" and price represent "y" the price in 2003 is $1.40 and in 2004 it was 1.50

so far i have m=y2-y1/x2-x1 so i think m= .10 but im not even sure if that is right and i know that i need to use the formula y=mx+b but i dont know how to put the problem in this form.... please help me

i need to find the slope of a line representing the change from 2003 to 2004 letting the year represent "x" and price represent "y" the price in 2003 is $1.40 and in 2004 it was 1.50

so far i have

m = (y2-y1)/(x2-x1) <<< This is correct

you have

x1 = 2003
y1 = 1.40

x2 = 2004
y2 = 1.50

Now use the equation above...
