 * //EQ: HOW DO YOU IDENTIFY SLOPE OF PARALLEL AND PERPENDICULAR LINES //

//FRIENDS //: //SLOPE INTERSET FORM, STANDERD FORM, COORDINATE PLANES, POINT SLOPE FORM OF A LINE //**

**//INTERESTS : COMMPARING COST, ROADS, INTERSECTING HIGHWAYS //**

**//EXAMPLES: //** **//(IDENTIFY WHICH LINES ARE PARALLEL)//**  **// X=7;Y=-5/6X+8;Y=-5/6X-4;X=-9 //**  //**(WRITE AN EQUATION IN SLOP-INTERCEPT FORM THE LINE THAT IS PARALLEL TO THE GIVEN LINE AND THAT PASSES THOUGH THE GIVEN POINT)**// Solution //**
 * // Solution //**
 * //Y=2X+3;(1,7)
