The point (-k, 3k) is on the terminal arm of an angle in standard position. State the exact value of the three primary trigonometric ratios in simplest form.

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 =
