Determine the slope of the lines from the options First option: y = 5x + 3, the slope is 5 Second option: y = (1/5)x + 3, the slope is 1/5 Third option: y = -5x + 3, the slope is -5 Fourth option: y = (-1/5)x + 3, the slope is -1/5
Parallel lines are similar in the slope. So the line which is parallel to line AB must have the slope of 5.
The answer is 3. Radius, because the radius of a circle is the length of a line from the centre of the circle to the edge of the circle. I hope this helps!
They are similar because they both show that if you have parenthesis with different numbers in them, they can be swapped around and switched with each other to be equal with a different type of switch.
