Start with the slope formula.

Slope formula can be read as the second y minus the first

y over the second x minus the first x.

So for this problem, the second y minus the first y would be

5 - 2 and the second x minus the first x would be 8 - 4.

5 - 2 over 8 - 4 is 3/4.

So the slope of the line that passes through these points is 3/4.

To solve for C, you have to get both of the numbers with a C on the same side. So, subtract the 5c from the right side onto the left side.

$8c = 5c + 21\\8c - 5c = 5c - 5c + 21\\3c = 21$

Then, divide by 3 on each side.

$3c = 21\\3c /3 = 21/3\\c = 7$

So, c = 7.

Answer:

$length=4\ cm\\width=6\ cm$

Step-by-step explanation:

Given the rectangular poster shown in the picture, you know that its dimensions (its width and its lenght) are:

$w_1=24\ cm\\l_1=16\ cm$

In order to calculate the dimensions of the rectangular at $\frac{1}{4}$ times its current size, you need to multiply the original lenght by $\frac{1}{4}$ and multiply the original width by $\frac{1}{4}$ .
