Start with the basic equation of a line:

y = mx + b

Since the slope m = 0, the equation becomes:

y = 0*x + b = b

where b is the y-intercept. To find the intercept, we take the equation:

y = 0*x + b and put the values of the point (-4, 7) into the equation:

7 = 0*(-4) + b, which means, b = 7. Our equation becomes:

y = 7

This means any value of x will produce the result y = 7. Graphically, it looks like:
