Line k contains the points (-9, 4) and (9,-8) in the xy-coordinate plane. What are two other points that on line k?

Depends on what x values you want to take.

Step-by-step explanation:

So, first, you got to know the equation of a line. y=mx+c

First we find m, the gradient. We find it by doing y2-y1/x2-x1/

we get 12/-18 which simplifies to 2/3. Now, this is our gradient

With this we have, y=2/9x + c. Now take a point that was given, substitute and you will get c. I took 9,-8 and got c as -14.
Now our equation is y=2/3x + (-14)/
Now we have to find two points on it. Here we can take whatever x values you want, substitute it, and get the y.

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
