What is an equation of a line that does not have an x-intercept in a y=mx+b form?

An equation of a line that does not have an x-intercept in a y=mx+b form would have a slope of 0.

Step-by-step explanation:

When an equation does not have an x-intercept, the slope will be 0, which would be a straight horizontal line. If it had no y-intercept, the slope would be undefined.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

not sure but it may be b, as i said i'm not sure.
