In the standard (x,y) coordinate plane, if the xcoordinate of each point on a line is 4 less than twice its ycoordinate, what is the slope of the line?

you could just pick two points that satisfy your given condition,
pick any y,
e.g. y = 4, then x = 4 > (4,4)
y = 5, then 6 > (6,5)
slope = (54)/(64) = 1/2
or
just translate "xcoordinate of each point on a line is 4 less than twice its ycoordinate"
> x = 2y  4
2y = x+4
y = (1/2)x + 2 compare with y = mx + b
slope = 1/2
