Li believes that the graph shows a direct variation. Why is Li incorrect in saying that the graph shows a direct variation?

padilas [110]

Answer:

Option 2) When the x-value is 0, the y-value is 1.

Step-by-step explanation:

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 <em>and the line passes through the origin </em>

Remember that in a direct variation

For x=0, the value of y is equal to zero too

therefore

The graph is not a direct variation , because

When the x-value is 0, the y-value is 1.

What is the answer to3= g/4 -5

blagie [28]

$3 = \frac{g}{4} - 5$

First, add '5' to both of the sides.
$3 + 5 = \frac{g}{4}$

Second, add '3 + 5' to get 8.
$8 = \frac{g}{4}$

Third, multiply both sides by '4' to get rid of the fraction.
$8 \times 4 = g$

Fourth, multiply '8 × 4' to get '32'.
$32 = g$

Fifth, you can switch your sides.
$g = 32$

Answer: $\fbox {g = 32}$
