slope dilemma

<p>I have a question about slope. If you have a line, lets say y=2x+5. And a question asks you to find the equation of the line of the relection of that line over the x-axis. What would the slope of that reflected line be in reference to my example?</p>

<p>bump .</p>

<p>I believe you just take the opposite of m. So if the slope is 2, then slope of the reflection is -2.</p>

<p>y = -2x-5, i believe. Draw it!</p>

y = -2x-5, i believe

I also believe so.</p>

<p>Yeah. I saw it in my head. </p>

<p>No, I'm not crazy.</p>

<p>What happens to the slope if the line is reflected in the y-axis?</p>

<p>if slope is x then reflect over y is 1/x i think so the slope should become y = 1/2(x) - 4</p>

<p>no, 1/x is nothing related to the original graph. Remember this: reflection over x is -f(x), reflection over y is f(-x) - or in your case, y = -2x +5.</p>
