Algebra.Com's Answer #272389 by mtmorro(23)![]() ![]() You can put this solution on YOUR website! To be able to find the equation of any line by finding the slope and y-intercept. Then the equation of the line must be written in slope-intercept form, y = mx+b. \n" ); document.write( " \r \n" ); document.write( "\n" ); document.write( "If we substitute 0 in for x in the equation y = mx+b, we get y = m(0)+b or y = b. Thus the graph will cross the y-axis at the point (0,b) \n" ); document.write( "For the equation y = x+2, m = 1 and b = 2. The graph crosses the y-axis at (0,2) and has a slope equal to 1. \n" ); document.write( " \r \n" ); document.write( "\n" ); document.write( "Here is a good link that will walk you thru it.. \r \n" ); document.write( "\n" ); document.write( "http://www.math.com/school/subject2/lessons/S2U4L2DP.html \r \n" ); document.write( "\n" ); document.write( "I am do not know how to add a graph on this anwser this will help you. \n" ); document.write( " |
