Background
A solution of a linear equation is an ordered pair
whose values make the equation true. To find a
solution, pick a value for x, substitute it into the
equation, and solve for y 
WarmUp y = 3x  7; (2,
) is a solution. matches 1
â€œReplace with 2; 3 times 2 is 6. 6 minus 7 is 1,
so the answer is 1.â€
