WebOct 24, 2024 · The horizontal line test is a method that can be used to determine if a function is a one-to-one function. This means that, for every y -value in the function, … WebLines with no tilt — horizontal lines — have zero slope (m = 0). In that case, we can write the line in a simpler way, as a constant function: y = b. The other constant in the slope-intercept form, b, is the y-intercept, and it simply tells where the line intersects with the y-axis. For this discussion, we will be more interested in the ... fitted tracksuitsWebA graph passes the horizontal test if every horizontal line crosses, or intersects it, at one or fewer points.
