Distance between A (2, -1) and (2,a) is 4 units. Find the value of a where a is positive.
kolezko [41]

Answer:

a = 3

Step-by-step explanation:

Calculate the distance d using the distance formula and equate to 4

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = (2, - 1) and (x₂, y₂ ) = (2, a)

d = \sqrt{(2-2)^2+(a+1)^2} = \sqrt{0+(a+1)^2} = \sqrt{(a+1)^2} = a + 1 then

a + 1 = 4 ( subtract 1 from both sides )

a = 3

What a reflection is done over the x-axis, how will the pre-image be affected
vitfil [10]
When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection) to see where the new figure will be located.
