Answer 1

A. y = -⅓x + 3

Explanation:

Find the equation of the graph bin slope-intercept form, y = mx + b. Where,

m = slope = ∆y/∆x

Using two points on the line, (0, 3) and (3, 2),

Slope (m) = (2 - 3)/(3 - 0) = -1/3

m = -⅓

b = y-intercept = 3 (the y-coordinate of the point where the line crosses the y-axis)

✅To write the equation, substitute m = -⅓ and b = 3 into y = mx + b

Thus:

y = -⅓x + 3
