Answer:

y = x - 2

Explanation:

To write the equation in the form y = mx + b, find the value of slope (m) and y-intercept (b) of the graph.

Slope (m) = change in y/change in x

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

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

m = 2/2

m = 1

y-intercept (b) = -2 (this is the point where the y-axis is intercepted by the line, at this point, x = 0)

✔️To write the equation, substitute m = 1 and b = -2 into y = mx + b

y = 1(x) + (-2)

y = x - 2
