Algebra.Com's Answer #745801 by addingup(3677)![]() ![]() You can put this solution on YOUR website! y = mx+b \n" ); document.write( "y = 10x+4 \n" ); document.write( "set x to 0: \n" ); document.write( "y = 10(0) + 4 \n" ); document.write( ". \n" ); document.write( "10*0 = 0, so: \n" ); document.write( "y = 4 \n" ); document.write( "OK, we've got one of our numbers. When x = 0 y = 4. We write this: (0, 4) and that's our first pair. \n" ); document.write( ". \n" ); document.write( "Now let's rewrite the equation and set y = 0: \n" ); document.write( "10x = -y + 4 \n" ); document.write( "x = (-y+4)/10 \n" ); document.write( "x = -0+4/10 \n" ); document.write( "-(0 + 4/10) makes -0.4. \n" ); document.write( "Now we can write the other pair: (-0.4, 0) \n" ); document.write( "These are called ordered pairs and can now be plotted. See plot below, draw a straight line joining the two points. \n" ); document.write( ". \n" ); document.write( "Parallel line Two lines are parallel if they have the same slope. \n" ); document.write( "We know our slope is 10 and our y-intercept you say is 8.
