first select any two points on the line

OpenStudy (shelby1290):

ok so i'll just go with (1,3) and (-2,-3)

OpenStudy (shelby1290):

will the next step have to be using the formula: y2-y1 / x2-x1 so, -3-3/ -2-1

OpenStudy (shelby1290):

-3-3=-6 -2-1= -3 -6/-3 =6/3

OpenStudy (shelby1290):

6 divided by 3= 2 3 divided by 3= 1 so m=2

OpenStudy (shelby1290):

y=2x+b (1,3) 3=2x+1+b b=3-(2)(1)

OpenStudy (shelby1290):

b= 1 y=2x+1

OpenStudy (shelby1290):

am i right?

OpenStudy (anonymous):

right :)
