Question 209421
3x-y=4,,,,obviously,,,3x-4=y,,,from  y=mx+b,,,,m=3
.
to  find  slope  without this, try  evaluating  two  points  on  graph
.
when  x=0,,y=-4,,,,,,,when  x=1,,,,y=-1
.
now,,,,m=(y2-y1)/(x2-x1) ={-4-(-1)}/{0-1} = -3/-1 = 3,,,,,,as  above
.
Remember  the  slope  is rise  over  run,  and  we  only have  to  review numerator if  denominator  is  +1.,,,,,,,,(-1-(-4)) =3
.
When  there  are  negatives, however,  it  is  best  to  use  full  formula
.
