Here is a system of linear equations: 4x+6y=-4
-2x-3y=-6

a) What is the solution to the system of equations? Use the substitution method and show your work
b) Explain what your answer in part a tells you about the association of the lines in the system ​

c. 1,233 miles

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

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.
