Write the equation of the line that has an x-intercept of -3 and passes through the point (-3, 7).

x = -3

Step-by-step explanation:

Since, the line has x-intercept of -3,

⇒ line passes through (-3, 0),

We know that,

The Slope of a line passes through and is,

Slope of the line passes through (-3, 0) and (-3, 7),

That is, the line is parallel to y-axis.

Let the equation of the line,

x = a, where, a is any constant,

Since, it is passes through (-3,0),

⇒ -3 = a

Hence, the equation of the line would be,
