Write an equation for the line that passes through ​(-9​,7​) and whose slope is undefined.Write the equation in the standard form where all coefficients are expressed as relatively prime integers.

To find the equation of a line with an undefined slope that passes through a given point, we can use the fact that a line with an undefined slope is a vertical line.

A vertical line has the equation of the form x = c, where c is the x-coordinate of any point on the line.

In this case, the line passes through the point (-9, 7), so the equation would be x = -9.

However, the given standard form of an equation for a line has the form Ax + By = C, where A, B, and C are relatively prime integers.

To convert the equation x = -9 into the standard form, we can multiply both sides of the equation by a common denominator, which cancels out the fraction, giving us:

1 * x = -9 * 1

Simplifying this equation, we have:

x = -9

Which can be written in the standard form as:

1x + 0y = -9

So, the equation for the line that passes through (-9, 7) with an undefined slope in standard form is:

x + 0y = -9

undefined slope means a vertical line. That is, the line x=k for some k.

So, what do you think that is here?
