Answer:
y = -3/2x +4
Explanation:
The line crosses the y-axis at y = 4. The coordinates of that point are (0, 4). This is the "start."
The line crosses a grid intersection again 2 units to the right and 3 units down at the point (2, 1).
The slope is the ratio of the vertical change to the horizontal change:
m = -3/2
Now, you have the information required to fill in the equation:
y = -3/2x +4
