1. The problem asks to find the equation in slope-intercept form $y=mx+b$ that matches the given table of values:
| x | y |
|---|----|
| 1 | -7 |
| 2 | -10|
| 3 | -13|
| 4 | -16|
2. First, calculate the slope $m$ using any two points, for example $(1,-7)$ and $(2,-10)$:
$$m=\frac{y_2 - y_1}{x_2 - x_1} = \frac{-10 - (-7)}{2 - 1} = \frac{-10 + 7}{1} = \frac{-3}{1} = -3$$
3. Now use the slope $m=-3$ and one point, say $(1,-7)$, to find the y-intercept $b$ by substituting into $y=mx+b$:
$$-7 = -3 \times 1 + b$$
$$-7 = -3 + b$$
Add 3 to both sides:
$$-7 + 3 = b$$
$$b = -4$$
4. Therefore, the equation is:
$$y = -3x - 4$$
5. Checking the options, this matches option c.
Final answer: $y = -3x - 4$
