Which equation represents the graph of the linear function?
A.
y = 4x + 4
B.
y = 4x − 4
C.
y = −4x + 4
D.
y = −4x − 4
The y intercept of the function shown is at -4........and it has a positive slope......
Answers C and D have negative slopes, so we can eliminate them
Answer A has a positive slope, but it has a positive y intercept
Thus, "B" is correct......
B is the correct answer
We have 2 points : (0 , -4) and (1, 0)
m = (0 - -4) / (1 - 0) = 4/1 = 4
Positive slope.
y = mx + b
y = 4x + b
b, which is the y-intercept, is -4
so y = 4x + -4 = 4x-4
