Question
If (-2, -9) translates to (-9, 2), then (-5, -1) translates to
- (1, 5)
- (-1,5)
- (-12,10)
- (5, -12)
Hint:
HINT – In translation, a point is displaced.
The correct answer is: (-12,10)
Let point is displaced ‘x’ units along x – axis and ‘y’ units along y – axis.
It is given that (-2, -9) → (-9, 2)
Þ (-2 + x , - 9 + y) = (-9, 2)
Þ - 2 + x = - 9 and - 9 + y = 2
Þ x = - 7 and y = 11
So, (x , y) → (x – 7 , y + 11)
So, (-5, -1) → (-5 – 7 , - 1 + 11) = (- 12 , 10)
Hence, (-5, -1) is translated to (- 12 , 10)

Segments OA and OB are radii of the semicircle above. Arc AB has length 3π and OA = 5. What is the value of x ?
A semicircle is formed when a lining passing through the center touches the circle's two ends. As a result of joining two semicircles, we get a circular shape.
A circle is a collection of points equidistant from the circle's center. A radius is a common distance between the center of a circle and its point.

The table above shows two pairs of values for the linear function f. The function can be written in the form 
, where a and b are constants. What is the value of a + b ?
Note:
We can take a different approach to solving the linear equations. The above method is called method of elimination. We may also use the method of substitution; which is finding the values one variable, say a , in terms of b , from the first equation and replacing this value in the second equation to get a linear equation in one variable , b . Then solve it to find b, and use it in the previous equation to find a.
