Your problem statement is in y=mx+b (slope intercept) form
\n" ); document.write( "m = slope = -4/5
\n" ); document.write( ".
\n" ); document.write( "The y intercept is the value of the y coordinate when x=0
\n" ); document.write( "So it is 1.
\n" ); document.write( ".
\n" ); document.write( "\"graph%28500%2C500%2C-5%2C5%2C-5%2C5%2C-4%2F5%2Ax+%2B+1%29\"
\n" ); document.write( ".
\n" ); document.write( "We know a negative slope means the line runs from the upper left to the lower right.
\n" ); document.write( "We can see that is the case by looking at the graph.
\n" ); document.write( ".
\n" ); document.write( "We also can consider the x intercept as a check.
\n" ); document.write( "The x intercept is the x coordinate when y=0.
\n" ); document.write( "0 = -4/5x + 1
\n" ); document.write( "Adding 4/5x to both sides
\n" ); document.write( "4/5x = 1
\n" ); document.write( "Multiply both sides by 5
\n" ); document.write( "4x = 5
\n" ); document.write( "Dividing both sides by 4
\n" ); document.write( "x = 5/4 = 1.25
\n" ); document.write( "So, we expect to cross the x intercept at 1.25, which we can see on the graph.
\n" ); document.write( "Of course, you can substitute other values that ought to be on the line and check to see if they're on the graph.
\n" ); document.write( "For example, if x=5, then y = -4/5*5 + 1 = -3.
\n" ); document.write( "That checks.
\n" ); document.write( "Done. \n" ); document.write( "
\n" );
