Consider the following pair of equations
1 answer:
Answer:
(-2 -3)
Step-by-step explanation:
(1) y = 3x + 3
(2) y = x - 1
Substitute the value of y from (1) into (2) 3x + 3 = x - 1
Subtract 3 from each side of the equation 3x = x - 4
Subtract x from each side of the equation 2x = -4
Divide each side of the equation by 2 (3) x = -2
Substitute the value of x from (3) into (2) y = -2 - 1
Combine like terms y = -3
The ordered pair that satisfies the equations is (-2, -3).
In the Figure, the red line is the graph of Equation (1), and the blue line is the graph of Equation (2). The point of intersection is at (-2, -3).
