(-1,3) and (2,-3). The first number in an ordered pair stands for x and the second for y.
\n" ); document.write( "The slope-intercept equation:
\n" ); document.write( "y= mx+b The slope is represented by the letter m. Let's find the slope:
\n" ); document.write( "m= (y_2-y_1)/(x_2-x_1) Remember this _ means sub, so y_2= big y little 2
\n" ); document.write( "m= (-3-3)/(2--1)
\n" ); document.write( "m= (-6)/(3)
\n" ); document.write( "m= -2
\n" ); document.write( "Now we need to find our y-intercept, represented in the equation by the letter b:
\n" ); document.write( "y= mx+b
\n" ); document.write( "If we take one of our ordered pairs (any of the two) we can plug it in for x and y and solve for b. Let's take the first pair, (-1, 3). We get
\n" ); document.write( "3= -2(-1)+b
\n" ); document.write( "3= 2+b subtract 2 on both sides:
\n" ); document.write( "b= 1 Now we have our intercept:
\n" ); document.write( "y-mx+b
\n" ); document.write( "y= -2x+1 These are your two pair of ordered points written in slope-intercept \n" ); document.write( "
\n" );
