Ax+by ability of+C=0 by ability of=-Ax-C y=(-A/B)x-C/B in -A/Bx ------- -A/B represent slope -C/B------it represent y intercept y=4x+10 comparing it with equation y=mx+b , b=10 & in case you opt to discover x-intercept additionally ,then y-4x=10 divide the two factors by ability of that component era that's in R.H.S so dividing by ability of 10 y/10-4x/10=a million 0r y/10 +x/(-5/2)=a million so y-intercept is in y/10 is 10 & once you evaluate it to b it is likewise 10 & x- intercept in x/(-5/2) is -5/2
