Find the equation of the line which is perpendicular to the line y=− 1 3 x+6 through the point (2,4)

nikklg [1K]

The equation of the perpendicular line is 13y=27-x

Step-by-step explanation:

Writing the given equation to slope-intercept form.

y=− 1 3 x+6

The slope of this line is 13

The perpendicular slope is -1/13

Using the new slope and the given point into the slope-intercept form to find the y-intercept.

4=-1/13(2)+c

2=-1/13+c

c=27/13

y=-1/13x+27/13

So the equation of the perpendicular line is 13y=27-x

Nitella [24]

Answer:

A. What is the percent of change from last year to this year.

Answer: The percent of change from last year to this year is:

$\frac{10.00 - 8.50}{8.50} \times 100$

$\frac{1.50}{8.50} \times 100$

$17.65 \%$

Therefore, the percent change from last year to this year is 17.65%

B. Is this a percent increase or decrease?

Answer: This is a percent increase.

C. If you have 25% off coupon to use on 10.00 ticket what is the cost?

Answer: The 25% of 10.00 is given below:

$\frac{25}{100} \times 10.00$

$0.25 \times 10.00$

$2.5$

Therefore, the cost is:

$10.00 -2.5 =7.5$
