You can put this solution on YOUR website!
your equation is 4y = 4
\n" ); document.write( "divide both sides of this equation by 4 to get:
\n" ); document.write( "y = 1
\n" ); document.write( "the slope intercept form of this equation is y = mx + b where m is the slope and b is the y intercept.
\n" ); document.write( "since x is not in the equation, this means that m must be equal to 0.
\n" ); document.write( "our equation becomes:
\n" ); document.write( "y = 0*x + 1 which simplifies to y = 1
\n" ); document.write( "the value of y will always be 1 regardless of the value of x.
\n" ); document.write( "the slope is also calculated as follows:
\n" ); document.write( "slope = (y2-y1) / (x2-x1)
\n" ); document.write( "x1,y1 are one point on the line.
\n" ); document.write( "x2,y2 are another point on the line.
\n" ); document.write( "pick any value for x and the value of y will be equal to 1.
\n" ); document.write( "assume x1 = 5 and x2 = 10
\n" ); document.write( "our 2 point pairs are:
\n" ); document.write( "5,1 and 10,1
\n" ); document.write( "y2-y1 = 0
\n" ); document.write( "x2-x1 = 5
\n" ); document.write( "slope = (y2-y1)/(x2-x1) = 0/5 = 0.
\n" ); document.write( "a graph of the equation of y = 1 is shown below:
\n" ); document.write( "\"graph%28400%2C400%2C-5%2C25%2C-2%2C2%2C1%29\"
\n" ); document.write( "the line at y = 1 is the graph of the equation of y = 1.
\n" ); document.write( "the slope is equal to 0 because there is no change in the value of y for any change in the value of x.\r
