Linear Equations Fadd6B
1. The problem is to find the equation representing the table of values and verify if the given equations and graphs are correct.
2. The general form of a linear equation is $$y = mx + b$$ where $m$ is the slope and $b$ is the y-intercept.
3. For each equation, check the slope and y-intercept and verify with the points given:
- For $y = 3x - 4$, slope $m=3$, y-intercept $b=-4$. Points (-1, -7) and (2, 2) satisfy:
$$3(-1) - 4 = -3 - 4 = -7$$
$$3(2) - 4 = 6 - 4 = 2$$
This matches the description.
- For $y = -4x + 1$, slope $m=-4$, y-intercept $b=1$. Points (0, 1) and (1, -3) satisfy:
$$-4(0) + 1 = 1$$
$$-4(1) + 1 = -4 + 1 = -3$$
This matches the description.
- For $y = - (0/x)$, this simplifies to $y=0$ (horizontal line through origin). The graph is a horizontal line at $y=0$ passing through (0,0), which is correct.
- For $y = -2x + 2$, slope $m=-2$, y-intercept $b=2$. Points (0, 2) and (1, 0) satisfy:
$$-2(0) + 2 = 2$$
$$-2(1) + 2 = -2 + 2 = 0$$
This matches the description.
4. Therefore, all given equations correctly represent their respective tables of values and graphs.
Final answer: Yes, the equations and graphs are correct.
