Y=mx+b m=slope b=y intercept, aka where the line crosses the y axis or where x=0
we can find the y axis by looking it crosses the y axis at 4 units up so b=4 y=mx+4 we also se another point (-5,0) when x=-5, y=0 0=m(-5)+4 solve for m 0=m(-5)+4 subtract 4 -4=m(-5) divide both sides by -5 -4/-5=4/5=m
