start with x - y = -5
\n" ); document.write( "subtract x from both sides of the equation to get -y = -x - 5
\n" ); document.write( "multiply both sides of the equation by -1 to get y = x + 5
\n" ); document.write( "the general form of the slope intercept form of the equation for a straight line is y = mx + b.
\n" ); document.write( "m is the slope.
\n" ); document.write( "b is the y-intercept.
\n" ); document.write( "in this problem, m = 1 is the slope and b = 5 is the y-intercept.
\n" ); document.write( "the slope intercept form of this equation is y = x + 5.
\n" ); document.write( "the graph of the equation is shown below.
\n" ); document.write( "both forms of the equation are shown.
\n" ); document.write( "they draw the same line since they are equivalent.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "two points on the line are used to find the slope.
\n" ); document.write( "the points are (0,5) and (5,10).
\n" ); document.write( "slope is (y2 - y1) / (x2 - x1)
\n" ); document.write( "assign (5,10) to (x2,y2) and assign (0,5) to (x1,y1).
\n" ); document.write( "slope = (y2-y1)/(x2-x1) = (10-5)/(5-0) = 5/5 = 1.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the y-intercept is the value of y when x is 0.
\n" ); document.write( "to find, set x to 0 and solve for y.
\n" ); document.write( "y = x + 5 becomes y = 5.
\n" ); document.write( "the y-intercept is 5 at the coordinate point of (0,5).\r
\n" ); document.write( "
