Medals, fans, etc will be given out.

nnesha · Answer

y =mx + b slope intercept form 
where m is slope and b is y-intercept 
so replace  m by -3 and x and y variables by ( 1,-2)

anonymous · Answer

so y = 1 x + -2

nnesha · Answer

nope  slope is not 1
x is one 
(x , y) 
replace m by -3 which is slope they gave you

nnesha · Answer

first you have to solve for b :)

anonymous · Answer

@Nnesha  how do i solve for b

nnesha · Answer

okay first replace m by -3 and x y by order pair (x,y)
