HOW WOULD WRITE THIS FROM POINT TO POINT ON A GRAPH \n" ); document.write( "y = -1.25x + 250; graph this equation from x=0 to x=200 \n" ); document.write( "*** \n" ); document.write( "Equation for a straight line: y=mx+b, m=slope, b=y-intercept \n" ); document.write( "For given equation:y = -1.25x + 250 \n" ); document.write( "Slope=-1.25=-1-1/4=-5/4 \n" ); document.write( "The equation can now read: y=(-5/4)x+250 \n" ); document.write( "y-intercept=250 \n" ); document.write( "So, you have the information you need to graph the line. \n" ); document.write( "One point on the line is 250 on the y-axis or (0,250) \n" ); document.write( "To get the second point, use the slope which=∆y/∆x=change in y/change in x=rise/run \n" ); document.write( "Starting from the y-intercept, go down 5 units, then to the right 4 units. \n" ); document.write( "Draw the line thru the two points. \n" ); document.write( "To check if the graph is correct, plug in to the equation a convenient x-value which would give you a point which is on the line you just drew if it is correct. \n" ); document.write( " \n" ); document.write( " |
