Answer:
1) Y = -4/3X - 1
2) Y = X
3) Y = 1/2X - 2
Step-by-step explanation:
For the first one: The graph can be seen starting at one point and intercepting the Y-axis at -1. By counting down and over, we can see that the coordinates go down by 4 and to the right by 3, which can be represented by -4/3. The Y-intercept is -1, which means the last part of the equation will be -1. From this, we get the equation: Y = -4/3X - 1.
For the second one: The line goes up by one and to the right by 1, which can be represented by 1/1X, or just X. The line's Y-intercept is 0, which does not need to be represented. This gives the final equation: Y = X.
For the third one: The line goes up by one and to the right by 2, which can be represented by 1/2. The line's Y-intercept is -2. This can be represented by the equation: Y = 1/2X - 2.
