last question
Write an equation of the line with the given properties. Your answer should be written in standard form.
m is undefined passing through P(−7, −9)
x = -7
To write the equation of a line in standard form, we need two pieces of information: the slope (m) of the line and a point (P) through which the line passes. In this case, we are given that the slope (m) is undefined (vertical line) and the point (P) is (-7,-9).
When the slope (m) is undefined, it means that the line is vertical, and the equation will be of the form x = a, where 'a' is the x-coordinate of the point through which the line passes.
In this case, as the line passes through P(-7, -9), the equation can be written as x = -7. This is the equation of the line in standard form.
