So we could have seen that. The slope is negative 2. So this part of f of x, we have y is equal to negative 2x, plus, and then the y-intercept is pretty straightforward. This is at 3, 1, 2, 3, plus negative 2x plus 3. So where we're, the part of f of x where clearly it equals negative 2 at some point of that, this part of f of x is defined by this line. Obviously, this part of f of x is not defined by that line. But to figure out the exact value, we just have to figure out when this line is equal to negative 2.
