Help please ;-; The values in the table represent a linear function.

Fittoniya [83]

Answer:

The function rule in slope-intercept form is:

$y = \frac{1}{2}x-\frac{7}{2}$

Step-by-step explanation:

The slope-intercept form of a function is given as:

$y = mx+b$

Here

m is the rate of change of function and b is the y-intercept

The rate of change is calculated as:

$m = \frac{difference\ in\ y}{difference\ in\ x}$

For this, any two pairs of input and output can be taken.

So using the pairs (1,-3) and (2,-1)

$m=\frac{2-1}{-1+3}\\=\frac{1}{2}$

Putting the value of slope in slope-intercept form

$y = \frac{1}{2}x+b$

Putting (1,-3) in the equation

$-3 = \frac{1}{2}(1)+b\\-3 = \frac{1}{2}+b\\b = -3-\frac{1}{2}\\b = \frac{-6-1}{2}\\b= \frac{-7}{2}$

Putting the value of b

$y = \frac{1}{2}x-\frac{7}{2}$

Hence,

The function rule in slope-intercept form is:

$y = \frac{1}{2}x-\frac{7}{2}$

How do you answer $9 ; 10%

Veronika [31]

<span>You can calculate percentages by first finding what 10% of a value is and then what 5 or 1% is. From there you can multiply to find multiples and then add to get the required percentage.</span>

Lincoln wants to mix 3/8 of a liter of red paint with 7/8 of a liter of blue paint to make purple paint. How many liters of purp

Wittaler [7]

Answer: 1 1/4

Step-by-step explanation:

Solving the fraction parts

3/8 + 7/8 = 10/8

Reducing the fraction part, 10/8

10/8= 5/4

Simplifying the fraction part, 5/4

5/4= 1 1/4
