document.write( "Question 802682: A line passes through the points (-1, -6) and (-4, 3). What is the equation of this line in slope-intercept form? \n" ); document.write( "
Algebra.Com's Answer #483982 by Cromlix(4381) You can put this solution on YOUR website! Slope (m) = y2 - y1/x2 - x1 \n" ); document.write( "Slope (m) = 3 - (-6)/-4 - (-1) \n" ); document.write( "Slope (m) = 9/-3 = -3 \n" ); document.write( "Using the equation y = mx + c \n" ); document.write( "with m = - 3 \n" ); document.write( "and coordinates (-4, 3) \n" ); document.write( "y = mx + c \n" ); document.write( "3 = -3(-4) + c \n" ); document.write( "c = 3 - 12 \n" ); document.write( "c = -9 \n" ); document.write( "y = -3x - 9 \n" ); document.write( "Hope this helps. \n" ); document.write( ":-) \n" ); document.write( " |
