Graphing Linear Equations Solution
Summary
To find the solution of two linear equations on a graph, identify the intersection point, which represents the values of x and y satisfying both equations. Verify by substituting these values into the original equations to ensure they hold true. For the given system, substituting y = 4 into y - 3x = -2 results in x = 2, confirming the solution as (2, 4).Full Conversation
Examine this system of linear equations.
y – 3x = –*,
y = *
Which is a solution of the system of equations?
(*, *)
(*, *)
(*, *)
(*, *)
Let's solve the system of equations:
*. \( y - 3x = -* \)
*. \( y = * \)
Substitute \( y = * \) into the first equation:
\[ * - 3x = -* \]
Solve for \( x \):
\[ * + * = 3x \]
\[ * = 3x \]
\[ x = * \]
So, the solution is \( (*, *) \).
