the equation of line L is y=mx+c , over here "c" is the y interceptb_roy13 wrote:In the XY plan, what is the Y intercpt of line L?
A-- The slope of line L is 3 times its Y intercept.
B-- The X intercept of line L is -1/3..
Need help..
the first statement says m = 3c .. insufficient
the second statement says x = -1/3 , that is when y =0, x=-1/3 .. insufficient ...
combining the 2 statements, we get y = -1/3m+c =0 that is m= 3c , which pretty much repeats the information in the first statement .. so the answer is E ...
