Answer:
AB = 5.8 units
Explanation:
The distance of line segment AB shown in the attachment below can be calculated using the distance formula, 
, assuming that each box in the graph equals 1 unit.
A(2, 4)
B(-3, 1)
Let,
Plug in the values into the distance formula
(nearest tenth)
AB = 5.8 units
Answer: D. changes direction
Explanation: A lens works by refraction: it bends light rays as they pass through it so they change direction.

Identify the explicit function for the sequence in the table. x:1, 2, 3, 4, 5, y: 8, 14, 20, 26, 32,

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
The answer is a hope this is helpful
Answer:
y=2x
Explanation:
In order for y to be 6, then x has to be half that value.
