Solve the following system of equations graphically. y - 4 = 0 2x - y - 2 = 0 What is the solution set? {(-3, -4)} {(-3, 4)} {(3, 4)} what does this mean {()} around the problem ????
Since the question is what is the solution set, the answers are sets. {} are the symbols for a set.
i also need help solving i think let me try
Have you tried graphing both equations?
so itd have to be C ???
First we solve both equations for y. y - 4 = 0 ----------> y = 4 2x - y - 2 = 0 ----------> y = 2x - 2
just so you know i didnt guess i worked it out
y = 4 is a horizontal line that goes through y = 4. To graph y = 2x - 2, we find two points and use them to graph the equation.
y = 2x - 2 x | y --------- 0 | -2 2 | 2
