Match each as either linear or non-linear. HELP

Virty [35]

Answer:

Linear

y=-x

$y = \frac{x}{9}$

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

Non linear

$y = \frac{4}{x}$

$\frac{2}{y} = x$

${x}^{2} + {y}^{2} = 1$

Step-by-step explanation:

Linear equations have the highest degree to be 1.

Therefore y=-x is linear.

$y = \frac{x}{9} \: is \: also \: linear.$

$y = \frac{4}{x} \implies \: xy = 4$

The degree of this equation is 2.

It is non-linear

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

is also linear.

$\frac{2}{y} = x \implies \: xy = 2....non - linear$

${x}^{2} + {y}^{2} = 1.....non - linear$

baherus [9]

Answer:

Riding is independent variable and cost is dependent....

Step-by-step explanation:

According to the given statement Jewels has $6.75 to ride the ferry around Connecticut. It will cost her $0.45 every time she rides.

It means that if she rides a ferry, she pays

If she does not ride the ferry she won't pay

This shows that the paying depends on riding.

Thus riding is independent variable and cost is dependent....

i hope i got it right

(QUICK!!!!!!!!!!!!) Write an equation of the line below.

Genrish500 [490]

Answer:

$\large\boxed{y=\dfrac{3}{5}x-2}$

Step-by-step explanation:

The slope-intercept form of an equation of aline:

$y=mx+b$

m - slope

b - y-intercept

The formula of a slope:

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

From the graph we have the points:

(-5, -5)

y-intercept (0, -2) → b = -2

Calculate the slope:

$m=\dfrac{-2-(-5)}{0-(-5)}=\dfrac{3}{5}$

Put the value of the slope and the y-intercept to the equation of a line:

$y=\dfrac{3}{5}x-2$
