B...because there is no y intercept because of the 0,0 then you just turn the other one into a fraction and because the 1 is negitive the fraction is negitive
1.) Is -4
2.) Is -1
I just took the test, So I know that's the right answer! :)
Hope this helps. :)
Y = -4x/5 + 13/5 would be the answer to 4x+5y=13
Y = how far up
x = how far along
m = Slope or Gradient (how steep the line is)
b = value of y when x=0
How do you find "m" and "b"?
b is easy: just see where the line crosses the Y axis.
m (the Slope) needs some calculation:
m = Change in Y/change in X
