Answer:

The slope is 2 and the y-intercept is 8.

Step-by-step explanation:

As shown by the graph, every unit (mark) on the graph is equal to 4 units. That said, the y-intercept is 8. You can now use the x-intercept and y-intercept (2 coordinates) to find the value of the graph's slope using the slope formula m = (y2 - y1) / (x2 - x1).

Answer:

Not entirely sure if this is right, but here goes nothing!

Step-by-step explanation:

The y-intercept of line <em>L</em> is 8. This is because the graph is going by 4's.

Here comes the tricky part - what is the slope?

To calculate slope, you must find the rise/run.

The rise/run is 2/1, so your slope is 2.

Your answer will be shown below:

(8, 2)

I hope this helps! Sorry if it didn't!

HELP!! PLEASE A carpenter is framing a window with wood trim where the length of the window is 9 and 1/3 feet. If the width of t

ohaa [14]

We need the perimeter of the window for framing

The window is in the shape of a rectangle with the height of $9 \frac{1}{3}$ feet and width of $6 \frac{3}{4}$ . The diagram of the shape is shown below

The perimeter of a shape is obtained by adding up the length of all the sides that form the shape.

The perimeter of the window is $9 \frac{1}{3}+9 \frac{1}{3}+6 \frac{3}{4}+6 \frac{3}{4}$ = $18 \frac{2}{3}+12 \frac{6}{4}$

We have two whole numbers 18 and 12 and two fractions $\frac{2}{3}$ and $\frac{6}{4}$

Adding the two fractions that have different denominator
$\frac{2}{3}+ \frac{6}{4} = \frac{8}{12}+ \frac{18}{12}= \frac{26}{12}$ , which is an improper fraction which we can change into a mixed number $2 \frac{1}{6}$

So the perimeter of the window is
$18+12+2 \frac{1}{6} =32 \frac{1}{6}$

and the length of wood needed for the frame is $32 \frac{1}{6}$ feet
