Need help with a math problem, image is below. Thank you

Answer:
y = 1/2x + 2
Step-by-step explanation:
y = mx + b
m = gradient
b = y intercept
First calculate the slope/gradient = Rise / Run
Rise / Run = 2/4 = 1/2
y intercept, when x= 0
y = 2
therefore equation of line
y = 1/2x + 2
hope this helps! :)
