This graph shows the plot of a piecewise function consisting of two lines intersecting at x = 4.

For the portion of the line where x < 4, we can see that it passes through the points (0, 1) and (1, 0).

To determine the equation, we can use the slope-intercept form of a linear equation, which is y = mx + b.
Plugging in the values from the first point, (0, 1), we get:

1 = m * 0 + b
1 = b

Substituting b = 1 into the equation, we have:

y = m * x + 1

Next, we can use the second point, (1, 0), to so...
