You can put this solution on YOUR website!
You can start by writing the slope-intercept form of a linear equation.
\n" ); document.write( "1) y = mx+b (m = slope, b = y-intercept)
\n" ); document.write( "You have been given the slope, m = 2, so now you can write:
\n" ); document.write( "2) y = 2x + b Now you need to find the value of b.
\n" ); document.write( "You can do this by substituting the x- and y-coordinates from the given point (4, -8) into equation 2) and solving for b.
\n" ); document.write( "-8 = 2(4) + b
\n" ); document.write( "-8 = 8 + b Subtract 8 from both sides.
\n" ); document.write( "-16 = b Now that you have b, you can write the final equation.
\n" ); document.write( " $\"highlight%28y+=+2x+-+16%29\"$ \n" ); document.write( "
