1. Problem Description

The problem asks us to identify which ordered pairs satisfy the equation y=67x+1y = \frac{6}{7}x + 1.

2. Solution Steps

To determine if an ordered pair (x,y)(x, y) satisfies the equation y=67x+1y = \frac{6}{7}x + 1, we substitute the xx and yy values into the equation and check if the equation holds true.
* (0, 1): 1=67(0)+11=0+11=11 = \frac{6}{7}(0) + 1 \Rightarrow 1 = 0 + 1 \Rightarrow 1 = 1. This is true.
* (4, -2): 2=67(4)+12=247+12=247+772=317-2 = \frac{6}{7}(4) + 1 \Rightarrow -2 = \frac{24}{7} + 1 \Rightarrow -2 = \frac{24}{7} + \frac{7}{7} \Rightarrow -2 = \frac{31}{7}. Since 2=147-2 = -\frac{14}{7}, this is false.
* (-7, -5): 5=67(7)+15=6+15=5-5 = \frac{6}{7}(-7) + 1 \Rightarrow -5 = -6 + 1 \Rightarrow -5 = -5. This is true.
* (-7, 6): 6=67(7)+16=6+16=56 = \frac{6}{7}(-7) + 1 \Rightarrow 6 = -6 + 1 \Rightarrow 6 = -5. This is false.
* (0, 7): 7=67(0)+17=0+17=17 = \frac{6}{7}(0) + 1 \Rightarrow 7 = 0 + 1 \Rightarrow 7 = 1. This is false.
* (5, 4): 4=67(5)+14=307+14=307+774=3774 = \frac{6}{7}(5) + 1 \Rightarrow 4 = \frac{30}{7} + 1 \Rightarrow 4 = \frac{30}{7} + \frac{7}{7} \Rightarrow 4 = \frac{37}{7}. Since 4=2874 = \frac{28}{7}, this is false.
Therefore, the ordered pairs that represent points on the graph of the equation are (0, 1) and (-7, -5).

3. Final Answer

(0, 1), (-7, -5)
