Reflect the point -2,2 over the line 3/4 x plus 3

To reflect the point \((-2, 2)\) over the line \(y = \frac{3}{4}x + 3\), we'll follow these steps:

1. **Find the slope of the perpendicular line**:  
   The slope of the given line \(y = \frac{3}{4}x + 3\) is \(\frac{3}{4}\).  
   The slope of the line perpendicular to it is the negative reciprocal, which is \(-\frac{4}{3}\).

2. **Write the equation of the perpendicular line**:  
   The equation of the perpendicular line passing through the point \((-2, 2)\) will be in the form \(y - y_1 = m(x - x_1)\), where \(m = -\frac{4}{3}\) is the slope and \((-2, 2)\) is the point.  
   So, we substitute:
   \[
   y - 2 = -\frac{4}{3}(x + 2)
   \]
   Simplify the equation to get the equation of the perpendicular line:
   \[
   y = -\frac{4}{3}x - \frac{8}{3} + 2
   \]
   \[
   y = -\frac{4}{3}x + \frac{2}{3}
   \]

3. **Find the intersection of the two lines**:  
   Now, we solve the system of equations to find the intersection of the line \(y = \frac{3}{4}x + 3\) and the perpendicular line \(y = -\frac{4}{3}x + \frac{2}{3}\).

   Set the equations equal to each other:
   \[
   \frac{3}{4}x + 3 = -\frac{4}{3}x + \frac{2}{3}
   \]
   Multiply through by 12 to eliminate the fractions:
   \[
   9x + 36 = -16x + 8
   \]
   Combine like terms:
   \[
   25x = -28
   \]
   So, \(x = -\frac{28}{25}\).

4. **Find the corresponding y-coordinate**:  
   Substitute \(x = -\frac{28}{25}\) into the equation of the original line \(y = \frac{3}{4}x + 3\):
   \[
   y = \frac{3}{4} \times -\frac{28}{25} + 3 = -\frac{84}{100} + 3 = -0.84 + 3 = 2.16
   \]
   So, the point of intersection is \(\left(-\frac{28}{25}, 2.16\right)\).

5. **Find the reflected point**:  
   The point \((-2, 2)\) and its reflection will be equidistant from the line. Using the formula for reflection, the reflected point will be \((-3.12, 2.32)\).

The reflection of the point \((-2, 2)\) over the line \(y = \frac{3}{4}x + 3\) is approximately \((-3.12, 2.32)\).
