This is about understanding rigid transformations.
<u><em>Option 4 is not a rigid transformation.</em></u>
- In mathematics, transformation could be;
Rigid Transformation; This includes reflection, rotation, translation.
Non - Rigid Transformation; This includes dilation and shear.
- Now, a transformation is said to be a rigid transformation when the newly transformed image retains the same shape and size as it was before it was transformed. Although it can change position.
Whereas, it is termed non - rigid transformation if the shape or size changes.
Let us look at the triangles in the option;
- Option 1; In this option, we see that the two triangles maintain the same shape and size and thus the transformation is rigid.
- Option 2; In this option, we see that the two triangles maintain the same shape and size and thus the transformation is rigid.
- Option 3; Similar to options 1 & 2, we see that the two triangles maintain the same shape and size and thus the transformation is rigid.
- Option 4; We see that one of the triangles is bigger than the other. Since the transformed triangle is not the same size as it was before transformation, then it is not a rigid transformation.

The amount of water for washing x cars is y = 12x, and 72 gallons would be needed to wash 6 cars.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
The standard form of a linear equation is given as:
y = mx + b
Where m is the rate of change and b is the y intercept (initial value of y)
Let y represent the amount of water Jaquan uses to wash x cars, Using the point (2, 24) and (5, 60):
y - 24 = [(60 - 24)/(5- 2)](x - 2)
y = 12x
For 6 cars:
y = 12(6) = 72
The amount of water for washing x cars is y = 12x, and 72 gallons would be needed to wash 6 cars.
