In the xy-plane, a line has slope 3 and x-intercept 5. What is the y-intercept of the line?  Choose the correct choice from the following:	A) -15	B) -3	C) 0	D) 3	E) 9
Let the line be represented by a general equation y=mx+b, where m = slope (3) and b=y intercept. We are also given the value of x-intercept 5.   Theory : y intercept represents the point on the line where the x=0, and x intercept represents the point on the line where the y=0.   Putting these values in the equation : 0 = 3*5 + b =&gt; b = -15. Hence -15.
