Given the system of linear equations.
1 answer:
Answer:
A) See below. The solution is y=x+1.
B) I chose the method of graphing because it is quick and easy. When there are integer solutions to the equations, they are generally easy to read from the graph. In this case, the system is dependent, so both equations graph as the same line.
Step-by-step explanation:
A) If you divide the first equation by 5, you get ...
... x = y - 1
If you add 1 to this equation, you get ...
... y = x + 1 . . . . . the same as the second equation.
Both of these equations graph as the same line. The solution set is all points on the line y=x+1.
B) Your sentences are above. (I keep the Desmos graphing calculator open in my browser all the time, so graphing is very fast.)
