Answer:
The explicit function is y = 6x + 2
Explanation:
Since the change in x, Δx is constant and Δx = 1 and also, the change in y, Δy is constant and Δy = 6, we use the equation of a straight line in gradient form.
So, (y - y₁)/(x - x₁) = Δy/Δx where x₁ = 1 and y₁ = 8
So, substituting the values of the variables into the equation, we have
(y - y₁)/(x - x₁) = Δy/Δx
(y - 8)/(x - 1) = 6/1
(y - 8)/(x - 1) = 6
cross-multiplying, we have
(y - 8) = 6(x - 1)
expanding the brackets, we have
y - 8 = 6x - 6
adding 8 to both sides of the equation, we have
y - 8 + 8 = 6x - 6 + 8
y + 0 = 6x + 2
y = 6x + 2
So, the explicit function is y = 6x + 2
Answer:
Asteroid 1997 XF11 is one mile wide.
Explanation:
The above statement is the statement that is too narrow in the passage. A "too narrow" statement is one that gives a detail of what the main passage is talking about. Also, it helps the reader to visualize a part of what the passage is talking about. Yet it does not still provide enough information for one to grasp the whole passage. Also, such statement gives a specific idea or concept from the story or passage.
The above statement is "too narrow" because it actually states a single part of the overall passage and also gives a very specific idea from the passage.
