You can put this solution on YOUR website!
YOU'VE BEEN GIVEN A POINT AND A SLOPE AND ASKED FOR AN EQUATION OF A LINE. THAT IS YOUR CLUE THAT YOU SHOULD USE THE POINT SLOPE FORMULA.
\n" ); document.write( "\"highlight%28y-y1=m%28x-x1%29%29\", where m=slope, and (x1,y1) is the given point.
\n" ); document.write( "Graph the line described: Through (-2,-3);m = 5/4
\n" ); document.write( "x1=-2, y1=-3, m=5/4
\n" ); document.write( "\"y-%28-3%29=%285%2F4%29%28x-%28-2%29%29\"
\n" ); document.write( "\"y%2B3=%285%2F4%29%28x%2B2%29\" Avoid adding fractions if you want by multiplying both sides by the LCD,4.
\n" ); document.write( "\"4%28y%2B3%29=4%285%2F4%29%28x%2B2%29\"
\n" ); document.write( "\"4y%2B12=5%28x%2B2%29\"
\n" ); document.write( "\"4y%2B12=5x%2B10\"
\n" ); document.write( "\"4y%2B12-12=5x%2B10-12\"
\n" ); document.write( "\"4y=5x-2\"
\n" ); document.write( "\"-5x%2B4y=-5x%2B5x-2\"
\n" ); document.write( "\"-5x%2B4y=-2\" This is the equation in standard form, but some books don't lead with a negative x. If this is the case, then multiply both sides of the equation by -1.
\n" ); document.write( "\"5x-4y=2\" Is also in standard form.
\n" ); document.write( "I forgot to graph this earlier, sorry.
\n" ); document.write( "Plot (-2,-3) , then use the slope=rise/run=5/4. Go up from that point and right 4 and plot a second point at (2,2). Connect the dots and you should have this line:
\n" ); document.write( "\"graph%28300%2C200%2C-10%2C10%2C-10%2C10%2C%285%2F4%29%28x%2B2%29-3%29\"
