domebotnos · Answer

the thing is , i dont get how to do this at all. i dont know how to find the equation i just started doing this

nikato · Answer

ok. have you learned the y-intercept equation?

y=mx+b
where m is your slope and b is you y-intercept

domebotnos · Answer

yea i remember a little bit about that i learned it last year but since this is a fresh new school year I'm kinda rusty

nikato · Answer

where y=mx+b 
m=slope
b=where the line intercepts the y-axis
(x,y)= a point part of the equation
