Answer:
The equation of the line that passes through the point (7,−3) and has an undefined slope will have the equation: x = 7.
Explanation:
As the line has an undefined slope, meaning the line is vertical.
As we know that the vertical line passes through (7, -3), so it can never pass through any x-value other than x = 7, although it can pass through infinite y-values.
so the equation of line will be: x = 7
Therefore, the equation of the line that passes through the point (7,−3) and has an undefined slope will have the equation: x = 7.
