A dilation with scale factor 3 gives the effect of stretching the line AB three times longer, as shown in the diagram below
The slope will stay the same as dilation does not change the direction of the line
If point O lies on AB and is the center of dilation, then the point O must also lie on A'B'
Answer:
the slope of A'B' = 3
A'B' passes through point O
The slope will stay the same as dilation does not change the direction of the line
If point O lies on AB and is the center of dilation, then the point O must also lie on A'B'
Answer:
the slope of A'B' = 3
A'B' passes through point O
