Answer:
y = 1/2x - 3
Explanation:
y = mx + b
You need to find the slope (m) and the y-intercept (b)
Slope:
Change in y over change in x
As y increases by 1, x is increasing by 2
slope = 1/2
y-intercept:
Select a point. It does not matter which one. I will choice (8,1) We will use the x and y values from this point and the slope 1/2 to find the y-intercept
y = mx + b
Use
y = 1 from the point (8,1)
x = 8 from the point (8,1)
m = 1/2
y = mx + b
1 = (1/2)(8) + b
1 = 4 + b Subtract 4 from both sides
-3 = b
y = 1/2 x - 3
