30 POINTS By looking at the intercepts, which linear function does the graph represent?

larisa86 [58]

C. f(x)=2/3x-2

<h2>Explanation:</h2>

Looking at the graph we realize that the y-intercept is given by:

$b=-2$

The Slope-intercept form of the equation of a line is given by:

$y=mx+b$

So, our equation becomes:

$y=mx-2$

So the only option that matches a negative y-intercept is C. Let's see that the slope $m=2/3$ . Look at the y-intercept, if you increase x by 3 units, then y increases by 2 units and goes from $x=-2$ to $x=0$ . In other words:

$Change \ in \ x=\Delta x=3 \\ \\ Change \ in \ y=\Delta y=2 \\ \\ \\ m=\frac{\Delta y}{\Delta x}=\frac{2}{3}$

You use 4 gallons of water on 30 plants. At that rate how much water will you need for 45 plants?

Alja [10]

You would use 6 gallons of water to water 45 plants
4=30
$\frac{45}{30}$ = $\frac{3}{2}$
$\frac{3}{2}$ of 4 gallons = 6 gallons
