this is also one of my math homework probems pleasee help!!
Data: (x,y) = (-6,-4), then x = -6, y = -4; m = 5 (slope)
the General line equation is: y = mx + b, where m=slope, and b = y intersept or the point of the line where x=0, and y cut the y axis
y=mx+b, from data we know x,y and m values, sustituing those
-4=5*-6+b, the b value will be
-4=-30+b ==>b=30-4 ==> b=26
from this data I can write a general line equation for a family of lines that passing at (0,26) point and slope 5 :
y=5x+26, for all x and y
