Put the following equation of a line into slope-intercept form, simplifying all fractions. 18x + 3y = -21

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 =

Reflect the point (7,0) across the y-axis

If a || b and e || f , what if the value of y ?
