Here&#39;s <span style="color:#27ae60;">A Very Important Equation</span>:</p> <p><span style="font-size:28px;"><strong>$$y=mx+c$$</strong></span></p> <p><strong><span style="color:#8e44ad;">Why is it so important?</span></strong></p> <p>Because it gives a crapton of information immediately. If you convert an equation into this form, this is what you get:</p> <ul> <li>$m =$ slope</li> <li>$c&nbsp;= y$-intercept</li> </ul> <p>And of course $y$ and $x$ represent the $y$ and $x$-coordinates of points that satisfy the equation.</p> <p><strong>Note</strong>: This equation is sometimes called <span style="color:#e74c3c;">slope-intercept form</span>.</p>
