The Y-intercept is where the line goes through the Y-line. In this case, the Y-intercept is -3.

Slope is y2-y1/x2-x1

(5,6) (0,-3)

6-(-3)=9

5-0=5

9/5 is the slope.

Answer:

slope = \frac{8}{5}, y-intercept = - 3

Step-by-step explanation:

to calculate the slope m use the gradient formula

m = ( y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, - 3) and (x₂, y₂ ) = (5,5) ← 2 points on the line

m = \frac{5+3}{5-0} = \frac{8}{5}

the y-intercept is the point where the line crosses the y-axis

that is (0, - 3) ⇒ y-intercept = - 3

Find the percent increase. Round to the nearest percent. From 13 friends to 16 friends
larisa86 [58]

The percentage increase; you'll need to take the new value and subtract it by the old value.

16 - 13 = 3

Next, you'll divide 3 by the original value.

3 ÷ 13 = 0.23

And multiply by 100

The percentage increase of friends is 23%

Styline menswear ordered short-sleeve shirts for $23 each and long-sleeve shirts for $28.50 each from Tommy Hilfiger. If the tot
Mice21 [21]

Styline menswear ordered short-sleeve shirts for $23 each and long-sleeve shirts for $28.50

short-sleeve shirts for $23

long-sleeve shirts for $28.50

Total cost = $9,862.50

Let x be the number of short - sleeve

and y be the number of long  - sleeve

Total shirts = 375

x + y = 375

23x + 28.50y = 9862.50

Now we solve for x  

x + y = 375 ( subtract x on both sides)

So y = 375 - x

Now plug in 375 -x for y in second equation

23x + 28.50y = 9862.50

23x + 28.50(375 - x ) = 9862.50

23x + 10687.5 - 28.50x = 9862.50

subtract 10687.5  from both sides

23x  - 28.50x = -825

-5.5x = -825 (divide -5.5 on both sides)

x = 150

So number of short-sleeve = 150
