Answer 6

y = mx + b slope intercept form where m is slope which is always with x and b is y-intercept
y = b here b is y-intercept "no x" meaning slope is 0 (horizontal line )
x= something (vertical line )
horizontal line = zeero slope
vertical = slope is undefined
undefined slope when denominator is 0 for example 4/0 , 2/0
