The function you've provided is $f(x) = 0.8x + 1$, which is a linear function.

• Slope: The coefficient of $x$, which is $0.8$, represents the slope of the line. This means for every 1 unit increase in $x$, $f(x)$ increases by 0.8.

• Y-intercept: The constant term, $1$, represents the y-intercept of the line, which means the line crosses the y-axis at the point $(0, 1)$.

Would you like to explore further how to graph this function, find its values for certain $x$-values, or anything else?
