Write the equation of the graph.

A, y - 3 = -1/2(x + 1)

Step-by-step explanation:

To solve this problem, write each equation in the slope intercept form.

y - 3 = -1/2(x + 1)

Distributing -1/2 across each value in the parentheses, we get y - 3 = -1/2x - 1/2.

Adding 3 to both sides, we get y = -1/2x + 2 1/2.

Now that we have our equation, look at the graph. Is the equation correct? Yes, it is. The y-intercept is 2 1/2, and the slope is -1/2.
