If (-3.5, y) is a solution to the equation 2x-5y=10, what is the value of y?
\n" ); document.write( ".
\n" ); document.write( "The provided point (-3.5, y) gives the a value of 'x' as -3.5
\n" ); document.write( "Substitute that into the given formula and solve for y:
\n" ); document.write( "2x-5y=10
\n" ); document.write( "2(-3.5)-5y=10
\n" ); document.write( "(-7)-5y=10
\n" ); document.write( "Adding 7 to both sides:
\n" ); document.write( "-5y=17
\n" ); document.write( "Finally, dividing both sides by -5:
\n" ); document.write( "y = -17/5
\n" ); document.write( "y = -3.4
\n" ); document.write( ".
