5 to 2 = __ to 4 and also 14 to 21 = __ to 15

nasty-shy [4]

1) Set up proportions for the ratios:

$\frac{5}{2} = \frac{x}{4}$

Cross multiply the fractions:

$2x = 20$

Divide both sides by 2 to get x by itself.

$x = 10$

5 to 2 is equal to 10 to 4.
------------
2) Set up proportions for the ratios:

$\frac{14}{21} = \frac{x}{15}$

Cross multiply the fractions:

$21x = 210$

Divide both sides by 21 to get x by itself:

$x = 10$

14 to 21 is equal to 10 to 15.
------------
OPTIONAL:
To make 2) easier to solve, simplify 14 to 21.

$\frac{14}{21} / \frac{7}{7} = \frac{2}{3}$

Then, continue with the problem as described above:

$\frac{2}{3} = \frac{x}{15}$

$3x = 30$

$x = 10$

Write an equation in slope intercept form (4,-2) (0,-5)

Zarrin [17]

Answer:

y=-7/4x+5

Step-by-step explanation:

The line contains points at (4,-2) and (0,-5)

(y1-y2) / (x1-x2) = slope

(4,-2) =(x1,y1)

(0,-5) = (x2,y2)

(-2-5) / (4-0)

-7 / 4 = -7/4

y= -7/4x + b

plug in points for x and y to find b

-2=-7/4(4)+b

-2=-7+b

5=b

y=-7/4x+5
