Which two days had a ratio of 2:5 computers sold? Looking for brainliest.
Marianna [84]

Answer:  A. Wed to Fri

We have a bunch of natural numbers and we're told a pair is in the ratio 2:5.

For natural numbers to have this ratio, the left number will be a multiple of two and the right number will be a multiple of five.

Our only option for a multiple of 5 is 15, Friday.  So we have

2:5 = x:15

and x = 15*2/5 = 6

which was Wednesday's number.  So we get Wed:Fri=6:15=2:5.

(-3,2) and ( 2,-13) slope intercept equation
Georgia [21]

Given:

The points are (-3, 2) and (2, -13).

To find:

Slope-intercept form of the equation.

Solution:

Here x_1=-3, y_1=2, x_2=2, y_2=-13.

Slope of the line:

$m=\frac{y_2-y_1}{x_2-x_1}

$m=\frac{-13-2}{2-(-3)}

$m=\frac{-15}{5}

m = -3

Using point-slope formula:

y-y_1=m(x-x_1)

y-2=-3(x-(-3))

y-2=-3(x+3)

y-2=-3x-9

Add 2 on both sides.

y-2+2=-3x-9+2

y=-3x-7

Slope-intercept form of the equation is y = -3x - 7.
