Answer:

The original Slope is y=-1/3x-2

The perpendicular slope would be y=3x+b

Step-by-step explanation:

Original Slope:

You already have the y-interecpet, (0,-2), and you know two points (0,-2) and (-6,0), so you can find the slope with (y1-y2)/(x1-x2) so in this case, it would be (0-(-2))/(-6-0)= -1/3 and you can find y=1/3x-2.

Perpendicular Slope:

The slope of any perpendicular line would be the reciprocal of the original. So the reciprocal of -1/3 is 3. The b can be any real number because no matter the y-intercept the slope would still be perpendicular

Answer:

<h2><em><u>5.71</u></em><em><u>%</u></em></h2>

Step-by-step explanation:

<em><u>Given</u></em><em><u>,</u></em>

Cost price of the car when Arjun bought = ₹ 3,50,000

Cost price of that same car after 1 year = ₹ 3,70,000

<em><u>So</u></em><em><u>,</u></em>

Amount of money increased on the car's price

= ₹ (3,70,000 - 3,50,000)

= ₹ 20,000

<em><u>Therefore</u></em><em><u>,</u></em><em><u> </u></em>

Percentage of increase on the car's price

=  \frac{20000}{350000}  \times 100

  • <em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>

=  \frac{2}{35}  \times 100

  • <em>[</em><em>On</em><em> </em><em>further</em><em> </em><em>Simplification</em><em>]</em>

= 5.7142......

= 5.71 (approx.)

<em><u>Hence</u></em><em><u>,</u></em>

<em><u>Percentage</u></em><em><u> </u></em><em><u>in</u></em><em><u> </u></em><em><u>increase</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em><em><u>car's</u></em><em><u> </u></em><em><u>price</u></em><em><u> </u></em><em><u>was</u></em><em><u> </u></em><em><u>5.71</u></em><em><u>%</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>
