Solved by pluggable solver: Graphing Linear Equations
In order to graph \"y=-1.5%2Ax%2B0\" we only need to plug in two points to draw the line
\n" ); document.write( "
\n" ); document.write( " So lets plug in some points
\n" ); document.write( "
\n" ); document.write( " Plug in x=-6
\n" ); document.write( "
\n" ); document.write( " \"y=-1.5%2A%28-6%29%2B0\"
\n" ); document.write( "
\n" ); document.write( " \"y=9%2B0\" Multiply
\n" ); document.write( "
\n" ); document.write( " \"y=9\" Add
\n" ); document.write( "
\n" ); document.write( " So here's one point (-6,9)
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " Now lets find another point
\n" ); document.write( "
\n" ); document.write( " Plug in x=-4
\n" ); document.write( "
\n" ); document.write( " \"y=-1.5%2A%28-4%29%2B0\"
\n" ); document.write( "
\n" ); document.write( " \"y=6%2B0\" Multiply
\n" ); document.write( "
\n" ); document.write( " \"y=6\" Add
\n" ); document.write( "
\n" ); document.write( " So here's another point (-4,6). Add this to our graph
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " Now draw a line through these points
\n" ); document.write( "
\n" ); document.write( " So this is the graph of \"y=-1.5%2Ax%2B0\" through the points (-6,9) and (-4,6)
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " So from the graph we can see that the slope is \"-1.5%2F1\" (which tells us that in order to go from point to point we have to start at one point and go down -1.5 units and to the right 1 units to get to the next point), the y-intercept is (0,\"0\")and the x-intercept is (\"0\",0)
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " We could graph this equation another way. Since \"b=0\" this tells us that the y-intercept (the point where the graph intersects with the y-axis) is (0,\"0\").
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " So we have one point (0,\"0\")
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " Now since the slope is \"-1.5%2F1\", this means that in order to go from point to point we can use the slope to do so. So starting at (0,\"0\"), we can go down 1.5 units
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " and to the right 1 units to get to our next point
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " Now draw a line through those points to graph \"y=-1.5%2Ax%2B0\"
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( " So this is the graph of \"y=-1.5%2Ax%2B0\" through the points (0,0) and (1,-1.5)
\n" ); document.write( "
