Answer:

a. (1,14) and (7,7)

b. slope = -1.2

Step-by-step explanation:

a. Use the points that are actually on the drawn line

(1,14) and (7,7)

b. Slope formula is :

$slope = ( y_{2} - y_{1}) \div ( x_{2} - x_{1})$

It doesnt matter which one is 1 or 2. I will take (1,14) as (x1, y1) and (7,7) as (x2, y2)

$slope = \frac{(7 - 14)}{(7 - 1)} \\ = \frac{ - 7}{6} = - 1.1667 = - 1.2$

(PLSSSS HELP) Determine which three out of the six points shown below are a solution to the equation x-3y=22 Plot the three poin

algol [13]

Answer:

$(-2,8)$ $(7,5)$ $(1,7)$

Step-by-step explanation:

Given

$x + 3y = 22$

Solving (a): The possible coordinates

We have:

$(x,y) = (-2,8)$

This gives:

$x + 3y = 22 \to -2 + 3 * 8$

$x + 3y = 22 \to -2 + 24$

$x + 3y = 22 \to 22$

(-2,8) is a point on the grid

$(x,y) = (7,5)$

This gives:

$x + 3y = 22 \to 7 + 3 * 5$

$x + 3y = 22 \to 7 + 15$

$x + 3y = 22 \to 22$

(7,5) is a point on the grid

$(x,y) = (-5,5)$

This gives:

$x + 3y = 22 \to -5 + 3 * 5$

$x + 3y = 22 \to -5 + 15$

$x + 3y = 22 \to 10$

(-5,5) is a not point on the grid

$(x,y) = (1,3)$

This gives:

$x + 3y = 22 \to 1 + 3 * 3$

$x + 3y = 22 \to 1 + 9$

$x + 3y = 22 \to 10$

(1,3) is a not point on the grid

$(x,y) = (1,7)$

This gives:

$x + 3y = 22 \to 1 + 3 * 7$

$x + 3y = 22 \to 1 + 21$

$x + 3y = 22 \to 22$

(1,7) is a point on the grid

So, we plot the following on the grid

$(-2,8)$ $(7,5)$ $(1,7)$

Anna‘s age is eight years less than four times her sisters age right in expression for Anna‘s age how old is Anna if her sister

mixer [17]

Anna's age will be equal to 6 years if her sister is five years old. The expression is Anna= 2T -4.

<h3>What is an expression?</h3>

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Anna‘s age is eight years less than four times her sister's age right in expression for Anna‘s age how old is Anna if her sister is five years old

The expression for Anna's age is given below:-

Anna's age= 2T-4

Sister = 5 years

Anna= 2T -4

T is my sister's age. Then Anna's age will be calculated as:-

2(5)-4 = 10 - 4 = 6 years

Therefore, Anna's age will be equal to 6 years if her sister is five years old. The expression is Anna= 2T -4.
