What is the equation of the line from the table shown? x -1 0 1 y 6 4 2 Question 3 options: y = 2x + 2 y = 1/2 x + 2 y = 1/2 x +

nignag [31]

Answer:

The equation of the line is $y+2x=4$

Step-by-step explanation:

The table shown below is :

$\left[\begin{array}{ccc}x&y\\-1&6\\0&4\\1&2\end{array}\right]$

thus , to find the equation of the line ,

we use the formula :

$\frac{y-y_{1} }{x-x_{1} } = \frac{y_{2} - y_{3} }{x_{2} -x_{3} }$

where,

$x$ and $y$ are the variables.

$x_{1} =-1 ; y_{1} = 6; \\x_{2}=0; y_{2} = 4;\\ x_{3}=1 ; y_{3} = 2 ;$

substituting the values in the equation, we get ,

$\frac{y-6}{x-(-1)} = \frac{4-2}{0-1} \\\frac{y-6}{x+1} = \frac{2}{-1} \\y-6=-2*(x+1)\\y-6= -2x-2\\y+2x=4$

∴ The equation of the line is $y+2x=4$

Find the unit rate. 5/8 ounce per 1/4 pint

Katena32 [7]

Answer: 2.5 ounces/ pint

You can firstly turn your fractions into decimals 5/8 is equal to .625 and 1/4 is .25

Then you can divide .625 by .25 which is 2.5, So the unit rate is 2.5 ounces per pint.

Right the slope intercept form for the line that travels through (4,-1) and is parallel to y=1/4x

ololo11 [35]

Answer:

Step-by-step explanation:

The slope is given to you by the line y = 1/4 x

The slope is just read as the number in front of x providing that the coefficient of y is 1. If that is not so, then you must divide by the coefficient in front of y. So far what you have is y = 1/4 x + b.

The second part of the question is to use the given point to find b.

x = 4

y = -1

b = ? substitute x and y to find b

y = 1/4 * 4 + b

- 1 = 1/4 * 4 + b

-1 = 1 + b

-2 = b

The equation of the line is y = 1/4 x - 2 Just to confirm this, I'm going to include the graph with the point 4,-1 on it.
