Hello from MrBillDoesMath!
Answer:
y = (1/6) x
Discussion:
Slope intercept form of a line is y = mx +b
Step 1: Find "m" ( the slope of the line)
m = change in y / change in x
= (2-3)/( 12-18 )
= -1/-6
= + 1/6
This means that y= (1/6) x + b
Step 2: Determine the value b
As the line goes through (12, 2) substitute x = 12 and y =2 in the above equation to get
y = (1/6)x + b =>
2 = (1/6) 12 + b =>
2 = 2 + b =>
b = 0
Conclusion: y = (1/6) x
Thank you,
MrB
