Write an equation of a ine in slope-intercept form that passes through a point (4,-6) and has a slope of -3.
Sindrei [870]

Answer:

y= -3x +6

Step-by-step explanation:

<u>slope-intercept form</u><u>:</u>

y=mx +c, where m is the slope and c is the y-intercept.

Given that the slope is -3, m= -3.

Susbt. m= -3 into the equation:

y= -3x +c

Since the line passes the point (4, -6),

(4, -6) lies on the line and must therefore satisfy the equation. Thus, susbt. (4, -6) into the equation to find the value of c.

y= -3x +c

when x=4, y= -6,

-6= -3(4) +c

-6= -12 +c

c= 12 -6

c= 6

Hence, the equation of the line is y= -3x +6.

Select the correct answer. This table shows information on types of fragrances sold to men and women in a day at a beauty supply
maria [59]

Answer: C. 27% of men like woody fragrances, and 45% of the people who like citrus fragrances are women

Step-by-step explanation:

Here, Given table,

                      Citrus                   Fruity               Woody

Men       :           27                        21                         18

Women :           22                       26                         15

Thus, The percentage of men like woody fragrances  

= \frac{\text{Number of men who like woody fragrance}}{\text{total number of Men}} \times 100

= \frac{18}{66}\times 100

= \frac{1800}{66}

= 27.2727..... %

≈ 27 %

Now, The percentage of men like woody fragrances  

= \frac{\text{Number of women who like citrus fragrance}}{\text{total number of persons who like citrus}} \times 100

= \frac{22}{49}\times 100

= \frac{2200}{49}

= 44.8979591837 %

≈ 45  %

Thus, Option C is correct.
