Because if you know where the line crosses the y axis (the y intercept) you can plot a point there. Then with slope you can count to your next plotted point. With the 2 points you can now draw your line.
If the original price is $49.99 and it is 30% off. You would want to find what 70% of 49.99 is in order to find the 30% of sale price. So once you do that you will find out that the answer is $34.99
Let me know if this helps! Good luck!
Answer:
Perimeter of rectangle = 140 cm.
Step-by-step explanation:
As we know that,
Rectangle is defined as a quadrilateral having opposite sides are equal and each angle are at 90°.
Let the length of rectangle = l
And the width = b
Therefore,
Perimeter of rectangle is given by = 2 (l × b)
From the question,
Given:
length = l = 17.5 cm
Width = b = 40 mm = 4 cm
( because 1 cm = 10 mm)
Perimeter of rectangle is given by = 2 (l × b) = 2(17.5 × 4) = 140 cm.
Hence, the perimeter of rectangle = 140 cm.
