Answer:
y=2
Step-by-step explanation:
The Y=0 Line is the X-axis, where there is no altitude. Adding 2 to zero shift the line up to pass through the point (0,2).
Plug in the point (1,6) into each answer choice.
A) f(n) = 5n - 1
f(1) = 5(1) - 1 = 5 - 1 = 4
(1,4) ≠ (1,6)
Answer choice A is incorrect.
B) f(n) = 5n + 1
f(1) = 5(1) + 1 = 5 + 1 = 6
(1,6) = (1,6)
Answer choice B is correct.
C) f(n) = 4n + 3
f(1) = 4(1) + 3 = 4 + 3 = 7
(1,7) ≠ (1,6)
Answer choice C is incorrect.
D) f(n) = 4n - 3
f(1) = 4(1) - 3 = 4 - 3 = 1
(1,1) ≠ (1,6)
Answer choice D is incorrect.
Your answer is B) f(n) = 5n + 1

Answer: y = —
x + 3
Step-by-step explanation:
The line crosses the y-axis at the point (0,3), making its y-intercept be +3.
The line is going downwards left to right, giving it a negative slope.
The line's slope is — because it is negative and it goes down 1, over 2.
Therefore, the line's equation is y = — x + 3
Answer:
x = 7
Step-by-step explanation:
all triangles add up to 180
(90 from the right angle)
90 + (4x) + (5x +27) = 180
117 + 9x = 180
<u>-117 - 117</u>
9x = 63
x = 63/9
x = 7
