Direct variations need help

Solnce55 [7]

Answer:

Part 11) The table represent a direct variation. The equation is $y=18x$

Part 12) The table represent a direct variation. The equation is $y=0.4x$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Part 11)

For x=0.5, y=9

Find the value of k

$k=y/x$ -----> $k=9/0.5=18$

For x=3, y=54

Find the value of k

$k=y/x$ -----> $k=54/3=18$

For x=-2, y=-36

Find the value of k

$k=y/x$ -----> $k=-36/-2=18$

For x=1, y=18

Find the value of k

$k=y/x$ -----> $k=18/1=18$

For x=-8, y=-144

Find the value of k

$k=y/x$ -----> $k=-144/-8=18$

The values of k is the same for each ordered pair

therefore

The table represent a direct variation

The linear equation is

$y=18x$

Part 12)

For x=-5, y=-2

Find the value of k

$k=y/x$ -----> $k=-2/-5=2/5=0.40$

For x=3, y=1.2

Find the value of k

$k=y/x$ -----> $k=1.2/3=0.40$

For x=-2, y=-0.8

Find the value of k

$k=y/x$ -----> $k=-0.8/-2=0.4$

For x=10, y=4

Find the value of k

$k=y/x$ -----> $k=4/10=0.4$

For x=20, y=8

Find the value of k

$k=y/x$ -----> $k=8/20=0.4$

The values of k is the same for each ordered pair

therefore

The table represent a direct variation

The linear equation is

$y=0.4x$

Find the equation of the line.<br> Use exact numbers.

Grace [21]

The equation would be y=2/3x+4

So to finish the equation, you would need the slope and the y-intercept. The y-intercept is where the line hits the y-axis. So it hits the y-axis at (0,4), making the y-intercept 4.

Next find the slope. Do this by picking two points and plugging it into the equation

y2-y1/x2-x1

(0,4) (3,6)

6-4/3-0

2/3

So it would be y=2/3x+4

Quick algebra 1 question for 50 points!

Mumz [18]

Answer:

y is equal to 24

Step-by-step explanation:

If y is directly proportional to x when x is equal to 5 and y is 12, then when you multiply 5 by 2 which is 10, y will be proportional to that when you multiply 12 by 2 which is 24
