Answer:

<h2>The graph has a domain of all real numbers.</h2><h2>The graph has a y-intercept at (0, 1).</h2>

Step-by-step explanation:

The given function is

$y=3x-1+2$

This is linear function, the domain and range of linear functions are always all real numbers, because they don't have any kind of restriction. So, the first option is right.

In addition, linear function are represented by a line which has interceptions with each axis. The interceptions with the vertical axis is when $x=0$ :

$y=3x-1+2\\y=3(0)+1=1$

So, the fourth option is right,

Similarly, the interception with the horizontal axis is when $y=0$ :

$0=3x-1+2\\-3x=+1\\x=-\frac{1}{3}$

This means the last option is not correct.

Therefore, all options that apply are

The graph has a domain of all real numbers.
The graph has a y-intercept at (0, 1).

Choose the equation that represents the graph below: (1 point) Graph of a line passing through points 0 comma 6 and 9 comma 0 y

aleksklad [387]

Answer:

Option C is correct.

Equation of a line $y=\frac{-2}{3}x+6$ passing through (0,6) and (9,0).

Explanation:

Given the two points (0, 6) and (9 ,0).

To find the equation for the given two points $(x_{1},y_{1})$ and $(x_{2},y_{2})$ is,

$y-y_{1}=m(x-x_{1})$ ; where m is the slope and is given by:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

First find the slope m:

$m=\frac{0-6}{9-0} =\frac{-6}{9} =\frac{-2}{3}$

Substitute this value in equation of line:

$y-6=\frac{-2}{3} (x-0)$ or

$y-6=\frac{-2}{3} x$

⇒ $y=\frac{-2}{3}x+6$

Therefore, the equation for the given point is: $y=\frac{-2}{3}x+6$

Which best represents the units of the average rate of change for the boiling point based on the amounts of ethylene glycol in t

mario62 [17]

Answer:

Option b. degrees Fahrenheit/(mililiters)

Step-by-step explanation:

we know that

The formula to calculate the average rate of change between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have that

the units of the y-axis are ${\°F}$

the units of the x-axis are ${ml}$

therefore

the units of the the average rate of change are

$m=\frac{\°F}{ml}$
