Write the equation of the line satisfying the given condition. Perpendicular to x = 4 and passing through the point (7, 2)
Prependicular to x = 4 means that the line will have a gradient of 0.
Passing through the point, (7,2) is handy, but all we need is the y co-ordinate.
The line is y = 2.
It satisfies the requirements.
