There is this question on my homework and it says: write and equation in standard form of the line that passes through (7,2) and has a y- intercept of -4\r
\n" ); document.write( "\n" ); document.write( "I know that standard form is Ax=By=C [it's Ax + By = C]and i'm thinking that you would make it (7,2) (0,4) and then it would go into Y2-Y1/X2-X1 form. And end up with -6/-7 and now I and don't know what to do from here.
\n" ); document.write( "-------------
\n" ); document.write( "The points are (7,2) and (0,-4)
\n" ); document.write( "slope m = diffy/diffx = -6/-7 = 6/7
\n" ); document.write( "----
\n" ); document.write( "You have the slope and the y-intercept, --> eqn is
\n" ); document.write( "y = (6/7)x + 4 (slope-intercept form)
\n" ); document.write( "Multiply by 7
\n" ); document.write( "7y = 6x + 28
\n" ); document.write( "6x - 7y = -28 (standard form)\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
