Algebra.Com's Answer #165292 by Earlsdon(6294)![]() ![]() ![]() You can put this solution on YOUR website! Starting with the general form of a linear equation in the slope-intercept form: \n" ); document.write( "y = mx+b Substitute m = 1 so you have: \n" ); document.write( "y = (1)x+b Now to find the value of b, substitute the x- and y-coordinates fom the given point (-1,-2) into the equation above and solve for b. \n" ); document.write( "-2 = -1+b Add 1 to both sides. \n" ); document.write( "-1 = b so that the final equation is: \n" ); document.write( "y = x-1 \n" ); document.write( " |
