Correct Solution: (2,3) Explanation: The solution should be given as an ordered pair.
Practice makes perfect
Let's take a close look to the given equations, identifying their slope m and y-intercept b.
ccc
Equation (I) & & Equation (II) [0.8em]
y= 2x+( - 1) & & y= 1x+ 1
To graph them, we will plot the y-intercepts and find a second point on each line using the slopes. Then we will connect the points with a straight edge.
We can see above that the lines intersect when x=2. However, when stating the solution to a system of equations, we must state the values of both x and y. The correct answer is (2,3).
