I think the equation would be y=32000(1/2x). The y intercept would be, (16000 , 1) (8000 , 2) (4000 , 3).

What is an equation of the line that passes through the points (-4, -1)(−4,−1) and (6, -1)(6,−1)?

Vlada [557]

$\boxed{y=-1}$

<h2>Explanation:</h2>

In order to solve this problem, let's remember the point-slope form of the equation of a line:

$y-y_{1}=m(x-x_{1}) \\ \\ m:slope \\ \\ (x_{1},y_{1}):A \ point \ on \ the \ line$

We know two points:

$(x_{1},y_{1})=(-4, -1) \\ \\ (x_{2},y_{2})=(6, -1)$

So:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ m=\frac{-1-(-1)}{6-(-4)} \\ \\ m=0$

So this is a constant line (slope equals zero). Therefore, every point has a y-coordinate $y=-1$ . In other words, the equation is:

$\boxed{y=-1}$

Y is inversy proportional to x. When y=7 , x=9 A) work out an equation connecting y and x? B) work out the value of y when x=21

natita [175]

Answer:

see explanation

Step-by-step explanation:

since y is inversely proportional to x the equation relating them is

y = $\frac{k}{x}$ ← k is the constant of proportionality

to find k use the given condition when y = 7, x = 9

k = yx = 7 × 9 = 63

y = $\frac{63}{x}$ ← is the equation connecting them

when x = 21, then

y = $\frac{63}{21}$ = 3

Which inverse operation would be used to verify the following equation?

DochEvi [55]

You would bring the division over to to other side. When we switch it to the other side, it turns into a multiplication (the opposite of division). So we go from:

102 / 3 = 34
to
102 = 34 * 3

Which is C for your multiple choice! :)
