Chapter 1 - Linear Functions - 1.3 Fundamentals of Graphing and Slope - 1.3 Exercises - Page 52: 52

incorrect Slope: $-\frac{1}{3}$ $y$-intercept: $(0,\frac{4}{3})$

$y=-\frac{1}{3}x+\frac{4}{3}$ The slope is the coefficient of $x$, and the constant term is the $y$ value in the $y$-intercept of $(0,y)$. Slope: $-\frac{1}{3}$ $y$-intercept: $(0,\frac{4}{3})$ The student was not correct. The student mixed up the slope and $y$ value of the $y$-intercept.
