<p>In the xy-plane, the line with the equation ax+by=1. where a and b are constants, intersects the y-axis where y=2. What is the value of b?</p>
<p>Here’s a hint: “intercepts the y-axis” is another way of telling you that x = 0 at that point (and y=2)…</p>
<p>When the line intercepts the y-axis, x=0.</p>
<p>Plug in for x and y,</p>
<p>2B=1</p>
<p>So B= 1/2</p>
