System<span> of </span>equations<span> are independent, if 2nd </span>equation<span> is not multiplication of first</span>equation<span> by some </span>number<span> . ... </span>Simplify<span> the 2nd </span>equation: ... y - 2x = -7<span> ... If </span>you solve<span> the </span>equations<span>algebraically and </span>you<span> get a </span>solution<span> such as 5=5, then ... If </span>you use<span> either method and </span>end<span> up with a</span>statement<span> that's always true i hope this helps</span>
Sample Response: Since the statement is true, there are an infinite number of solutions to the system. This statement also indicates that the lines are equivalent.
When rotating a point 90 degrees counterclockwise about the origin our point A(x,y) becomes A'(-y,x). In other words, switch x and y and make y negative.
