How do you write an equation for a line that passes through a(-3,-7) and parallel to the x-axis

The equation would be y = -7

Step-by-step explanation:

Lines that are parallel to the x-axis have no slope and therefore can be written as y = (a number). That number can be found as the y-value in the ordered pair.

y = -7

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
