Algebra.Com's Answer #108790 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! FIND THE EQUATION OF THE LINE DETERMINED BY THE GIVEN INFORMATION. 1. M=1; P=(-7,0) 2. P1=(4,-5); P2=(11,2) 3. P1=(0,6); P2=(-2,3) 4. M=2; P=(0,1) \n" ); document.write( "----------------- \n" ); document.write( "Line equations look like this: y = mx + b \n" ); document.write( "m is the slope \n" ); document.write( "b is the y-intercept; it is the value of y when x = 0. \n" ); document.write( "---------------- \n" ); document.write( "1. M=1; P=(-7,0) \n" ); document.write( "You are told the slope is 1 and y = 0 when x = -7 \n" ); document.write( "Put those numbers into y = mx + b to solve for \"b\": \n" ); document.write( "0 = 1*-7 + b \n" ); document.write( "b = 7 \n" ); document.write( "EQUATION: y = x + 7 \n" ); document.write( "------------------------ \n" ); document.write( "2. P1=(4,-5); P2=(11,2) 3. P1=(0,6); P2=(-2,3) \n" ); document.write( "These cannot be worked because you only have one point to work with \n" ); document.write( "------------------------ \n" ); document.write( "4. M=2; P=(0,1) \n" ); document.write( "slope = 2 \n" ); document.write( "1 = 2*0 + b \n" ); document.write( "b = 1 \n" ); document.write( "EQUATION: \n" ); document.write( "y = 2x + 1 \n" ); document.write( "================= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
