Answer 2

Finding the Intersection Point of Two Functions

To find the coordinates of the intersection point of the functions \(y=5x+4\) and \(y=4x-7\), we can set the two functions equal to each other and solve for the value of \(x\).

Step 1: Set the two functions equal to each other: \[5x+4 = 4x-7\]

Step 2: Solve for \(x\): \[5x - 4x = -7 - 4\] \[x = -11\]

Now that we have the value of \(x\), we can find the value of \(y\) by substituting \(x=-11\) into either of the original functions.

Step 3: Substitute \(x=-11\) into \(y=5x+4\): \[y = 5(-11) + 4\] \[y = -55 + 4\] \[y = -51\]

Therefore, the coordinates of the intersection point of the two functions are \((-11, -51)\).

This information is based on the mathematical principles of solving for the intersection point of two functions
