Algebra.Com's Answer #54308 by bucky(2189)![]() ![]() ![]() You can put this solution on YOUR website! If you can \"rework\" the equation into the form y = mx + b, then you will be able to identify the \n" ); document.write( "slope and the y-intercept. The slope is m, the multiplier of x, and the y-intercept \n" ); document.write( "is b, the constant that follows the x term. So let's work on the equation. You are given: \n" ); document.write( ". \n" ); document.write( "2y=5(x+1) \n" ); document.write( ". \n" ); document.write( "Multiply out the right side and the equation becomes: \n" ); document.write( ". \n" ); document.write( "2y = 5x + 5 \n" ); document.write( ". \n" ); document.write( "Close to what we need, but we need the solution for y ... not for 2y. So let's divide \n" ); document.write( "every term on both sides by 2. When we do, we get: \n" ); document.write( ". \n" ); document.write( "y = (5/2)*x + 5/2 \n" ); document.write( ". \n" ); document.write( "This is exactly in the form y = mx + b which is called the slope-intercept form. \n" ); document.write( ". \n" ); document.write( "By comparing our equation with the slope-intercept form, we can see that m, the multiplier \n" ); document.write( "of x is (5/2). And m is the slope. So the slope is (5/2). Then by comparing again we \n" ); document.write( "see that b is the constant on the right side. So b, which is the y-intercept, is also \n" ); document.write( "5/2. So the slope is 5/2 and so is the y-intercept. \n" ); document.write( ". \n" ); document.write( "Hope this helps you become more familiar with the slope-intercept form of linear equations. \n" ); document.write( " |
