Answer:
y + 3 = (2/3)(x + 3)
Explanation:
We can read the y-intercept directly from the graph: (0, -1). Another point on this line is (3, 1). As we move from the point (0, -1) to the point (3, 1), x increases by 3 and y increases by 2. Thus, the slope of this line is
m = rise / run = 2/3.
Starting from the general point-slope form of the equation of a straight line:
y - k = m(x - h), where (h, k) is a point on the line and m is the slope, we get:
y - [-3] = (2/3)(x - [-3]), or y + 3 = (2/3)(x + 3)
