All are possible as a ratio

A.
60%=60/100=6/10=3/5
5-3=2
concentrate to water=3:2

B.
3/5=water
2/5=concentrate
conctrate to water is 2:3

C. difference is 4 cups
5 cups and 1 cup
5:1
duh

if these are all ways to describe 1 ratio, then it depends on which one is bigger
C is anbibuous, it could mean that concentrate is 4 cups more than water or that water is 4 cups more than concentrate

and then we would use the w,x,y,z to find which one it is
it would be 3 cups then

the answer would be that it would be mix Y because 6:9=2:3
that means that the conctrate is smaller
then that means A is not possible since 60%>50% and concentrate is clearlly less than water

A is wrong

A line with a slope of 4 passes through the point (2, 1). What is the equation of this line?

olasank [31]

Answer:

point slope form: y - 1 = 4 (x -2)

slope intercept form: y = 4x -7

Step-by-step explanation:

If you want it in point slope form it would be: y - 1 = 4 (x -2)

but if you want it in slope intercept form, you solve this equation

y -1 = 4 (x-2)

y-1 = 4x -8

+1 +1

y = 4x -7 in slope intercept form

Question 1: Option B: $y=\frac{1}{3}x -2$

Question 2: Option D: $y+1=3 (x+1)$

Solution:

Question 1:

The point on the given line are (2, 4) and (4, –2).

Slope of the given line:

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

$$m=\frac{-2-4}{4-2}$

m = –3.

Slope of perpendicular line = –1 ÷ Slope of the given line

Slope of perpendicular line = $\frac{1}{3}$

Perpendicular line passing through the point (3, 1).

Slope -intercept form using point slope formula,

$y-y_1=m(x-x_1)$

$y-1=\frac{1}{3} (x-3)$

$y-1=\frac{1}{3} x-1$

$y=\frac{1}{3}x -2$

Option B is the correct answer.

Question 2:

The point on the given line are (0, –3) and (2, 3).

Slope of the given line:

$$m=\frac{3+3}{2-0}$

$$m=\frac{6}{2}$

m = 3.

Slope of parallel lines are equal.

Slope of parallel line =3

parallel lines passing through the point (–1, –1).

Point slope formula:

$y-y_1=m(x-x_1)$

$y+1=3 (x+1)$

Option D is the correct answer.
