<PRE><B>Question 3192</B>
Start with the basic equation of a line:&lt;br&gt;
y = mx + b&lt;br&gt;
Since the slope m = 0, the equation becomes:&lt;br&gt;
y = 0*x + b = b&lt;br&gt;
where b is the y-intercept. To find the intercept, we take the equation:&lt;br&gt;
y = 0*x + b and put the values of the point (-4, 7) into the equation:&lt;br&gt;
7 = 0*(-4) + b, which means, b = 7. Our equation becomes:&lt;br&gt;
y = 7&lt;br&gt;
This means any value of x will produce the result y = 7. Graphically, it looks like:&lt;br&gt;
