What is the y-intercept for the equation below?
7x + 2y = -12

Multiplying an even number of negative numbers gives an answer that is choose from:

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =
