Find Slope:
----------------------------------------------------------------


----------------------------------------------------------------
Substitute Slope = 1 into y = mx + b:
----------------------------------------------------------------
y = x + b
----------------------------------------------------------------
Find y-intercept:
----------------------------------------------------------------
At point (0, 2),
2 = 0 + b
b = 2
----------------------------------------------------------------
Substitute b = 2 into y = x + b:
----------------------------------------------------------------
y = x + 2
----------------------------------------------------------------
Expressed in the form of y = mx + b:
----------------------------------------------------------------
y = x + 2
----------------------------------------------------------------
Value of m + b :
----------------------------------------------------------------
1 + 2 = 3
----------------------------------------------------------------
Answer: The value of m+b is 3.----------------------------------------------------------------
