Answer:

slope = $\frac{1}{5}$

Step-by-step explanation:

calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (9, 6 ) and (x₂, y₂ ) = (4, 5 )

m = $\frac{5-6}{4-9}$ = $\frac{-1}{-5}$ = $\frac{1}{5}$

What is 15% of 135, show your work

SIZIF [17.4K]

Answer:

20.25

Step-by-step explanation:

Percentage solution with steps:

Step 1: Our output value is 135.

Step 2: We represent the unknown value with $x$

Step 3: From step 1 above,$135=100\%$

Step 4: Similarly, $x=15.\%$

Step 5: This results in a pair of simple equations:

$135=100\%(1)$.

$x=15.\%(2)$

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{135}{x}=\frac{100\%}{15.\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{135}=\frac{15.}{100}$

$\Rightarrow x=20.25$Therefore, $15.\%$ of $135$ is

How do I Find the slope and Y intercept of each equation:

Nesterboy [21]

$1.\\ \\ the \ slope \ intercept \ form \ is : \\ \\ y= mx +b \\ \\y=2x+1 \\ \\ the \ slope \ (the multiplier \ of \ x \ represented \ by \ m ) \ is \ 2 \\ \\ and \ the \ y-intercept \ (the constantrepresented \ by \ b \ ) \ is \ 1$

$2.\\ \\ y= \frac{1}{3}x-3 \\ \\ the \ slope \ m = \frac{1}{3} \ \ and \ y = -3$

$3.\\ \\ y= -2x + 1\\ \\ the \ slope \ m = -2 \ \ and \ y = 1$

$4.\\ \\-2x +5y=10\\ \\5y=2x +10 \ \ /:5\\ \\y = \frac{2}{5}x +2\\ \\ the \ slope \ m =\frac{ 2}{5} \ \ and \ y = 2$

$5.\\ \\ 4x-2y-5=0\\ \\-2y =-4x +5 \ \ /:(-2)\\ \\y=2x-\frac{5}{2} \\ \\ the \ slope \ m = 2 \ \ and \ y = -\frac{5}{ 2}$

$6.\\ \\ y=-4x-3 \\ \\ the \ slope \ m =-4 \ \ and \ y = -3$

$7.\\ \\3x-5y=20\\ \\-5y=-3x +20 \ \ / :(-5) \\ \\ y= \frac{3}{5}x - 4\\ \\ the \ slope \ m = \frac{3}{5} \ \ and \ y = -4$

Answer:

Sorry if this doesn't help:

Step-by-step explanation:

1, Order the data from least to greatest.

2, Find the median.

3, Calculate the median of both the lower and upper half of the data.

4, The IQR is the difference between the upper and lower medians.

Good luck!
