Question 32441
the equation y=mx+b defines the line with a slope of m. b is the y intercept.

therefore in the equation 3x+y=3 becomes y=-3x+3 or the slope is -3 the y intercept in +3 and solving the equation for x by setting y=0 we get
3x=3 or x=3/3 or x=1 the coordinates of this line are (0,3)(1,0) with a slope of -3.
