A pair of equations is shown below: y = 8x − 9 y = 4x − 1 Part A: Explain how you will solve the pair of equations by substituti
on or elimination. Show all the steps and write the solution. (5 points) Part B: If the two equations are graphed, at what point will the lines representing the two equations intersect? Explain your answer. (5 points) Part A, so to start off this problem i used substitution... after, this is some of the math used to solve this promblem y = 8x - 9 y = 4x - 1 8x - 9 = 4x - 1 ... so after that u can see i was just using substitution so now lets move on to the next step..
It could sometimes be proportional. The reasoning here is that if all the items have different prices it won't be, however if the items you are ordering all have the same price they will be!
