<p>In the xy-plane,the graph of the function h is a line. If h(-1) = 4 and h(5) = 1, what is the value of h(0)?</p>
<p>1)2.0
2)2.2
3)3.3
4)3.5
5)3.7</p>
<p>How can we get h(0) even though we aren't given much information here.</p>
<p>can you tell me if the answer is 4) 3.5 ?</p>
<p>It will take 1 minute to answer this problem.</p>
<p>Find the slope: -1/2</p>
<p>Form a equation.</p>
<p>Plug in 0 to the equation</p>
<p>You get 3.5 (which is the y-intercept)</p>
<p>The key is to find the y-intercept, because that is where the x value is 0.</p>
<p>Start by finding the slope. You have two points: (-1,4) and (5,1). Use the formula (y2-y1)/(x2-x1) -> (1-4)/(5-(-1)) = -3/6 = -1/2. </p>
<p>Now set up the equation in slope-intercept form:</p>
<p>y=mx+b
y=(-1/2)x+b</p>
<p>Remember, the goal is to find the y-intercept, so we have to solve for b. Plug in one of the points above (either one will work; I’ll use the first one).</p>
<p>4=(-1/2)(-1)+b
b=3.5</p>
<p>So the h(0) is 3.5, choice 4.</p>
<p>Find slope with the points given. Plug in. Get money; get paid.</p>
<p>Yeh your right nothingto and others thanks alot it makes perfect sense :).
Its good to add to the database solutions to problem,so I go in sat have almost all ideas in head :).</p>
