The shape of a heart is reflected across the x-axis. If the point at the bottom of the heart for the original figure is at (3 1/4,7 1/2) , what are the coordinates for the point at the bottom of the heart in the reflected image?(1 point)

To reflect a point across the x-axis, you change the sign of the y-coordinate while keeping the x-coordinate the same.

The original point at the bottom of the heart is given in mixed fractions as \( (3 \frac{1}{4}, 7 \frac{1}{2}) \).

First, we need to convert these mixed fractions to improper fractions or decimal form:

  • \( 3 \frac{1}{4} = \frac{13}{4} \) or \( 3.25 \)
  • \( 7 \frac{1}{2} = \frac{15}{2} \) or \( 7.5 \)

Now we will reflect the point \( (\frac{13}{4}, \frac{15}{2}) \) across the x-axis:

  • The x-coordinate remains \( \frac{13}{4} \).
  • The y-coordinate changes from \( \frac{15}{2} \) to \( -\frac{15}{2} \).

Thus, the coordinates for the reflected image of the point at the bottom of the heart will be:

\[ \left( \frac{13}{4}, -\frac{15}{2} \right) \]

Therefore, the final answer is:

\(( \frac{13}{4}, -\frac{15}{2} )\)
