Randolph is creating parallelogram WXYZ so that XY has an equation of y = 2 over 3x −5. Segment WZ must pass through the point (−6, −1). Which of the following is the equation for WZ? y − (−6) = 2 over 3(x − (−1))

y − (−1) = 2 over 3(x − (−6))

y − (−6) = 3 over 2(x − (−1))

y − (−1) = 3 over 2(x − (−6))

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
