1. **State the problem:** We are given two functions: Function 1 represented by points on a graph and Function 2 represented by a table of values. We need to determine which statement about their slopes and y-intercepts is true.
2. **Find the slope and y-intercept of Function 1:**
- From the graph, two points on Function 1 are $(-1, -4)$ and $(2, 3)$.
- The slope formula is $$m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{3 - (-4)}{2 - (-1)} = \frac{7}{3}.$$
- To find the y-intercept, use point-slope form with point $(2,3)$:
$$y = mx + b \Rightarrow 3 = \frac{7}{3} \times 2 + b \Rightarrow 3 = \frac{14}{3} + b.$$
- Solve for $b$:
$$b = 3 - \frac{14}{3} = \frac{9}{3} - \frac{14}{3} = -\frac{5}{3}.$$
3. **Find the slope and y-intercept of Function 2:**
- From the table, points are $(-2,1)$ and $(-1,8)$.
- Calculate slope:
$$m = \frac{8 - 1}{-1 - (-2)} = \frac{7}{1} = 7.$$
- Find y-intercept by using point $(-2,1)$:
$$1 = 7 \times (-2) + b \Rightarrow 1 = -14 + b.$$
- Solve for $b$:
$$b = 1 + 14 = 15.$$
4. **Compare slopes and y-intercepts:**
- Function 1 slope: $\frac{7}{3} \approx 2.33$; y-intercept: $-\frac{5}{3} \approx -1.67$.
- Function 2 slope: $7$; y-intercept: $15$.
- Function 1 has a smaller slope and smaller y-intercept than Function 2.
5. **Conclusion:** The correct statement is:
C. Function 1 has a smaller slope and y-intercept than Function 2.
