What is the equation of the line that passes through the points (-4,8) and (2,-1)

Mathematics
1 answer:
DiKsa [7]3 years ago
8 0

Answer:

y - 8 = (3/2)(x + 4)

Step-by-step explanation:

As we move from (-4, 8) to (2, -1), x increases by 6 (this is the run) and y decreases by 9 (this is the "rise").  Thus, the slope is

m = rise / run = 9/6, or 3/2.

Using the point-slope form of the equation of a straight line, we get:

y - 8 = (3/2)(x + 4)

Answer:

-5

-3

-2

Rule:  Subtract 2 from the input value

Step-by-step explanation:

Examine the pattern of the input and the corresponding output for the two given ordered pairs:

Input -2 → Output -4  

Output - Input =  -4 - (-2) = -2

Input 1 → Output -1

Output - Input = -1 - 1 = -2

Therefore to get the output value (y-value), we subtract 2 from the input value (x-value).

\begin{array}{| c | c |}\cline{1-2} x & y \\\cline{1-2} -3 & -5 \\\cline{1-2} -2 & -4 \\\cline{1-2} -1 & -3 \\\cline{1-2} 0 & -2\\\cline{1-2} 1 & -1 \\\cline{1-2}\end{array}

As the rule for the function is the subtract 2 from the input value to get the output value, we can write this as:

Output = Input - 2

or as an equation:  y=x-2

Ten less than three times the sum of x and seven is twenty-six.
Orlov [11]

Answer:

<u>x = 12</u>

Step-by-step explanation:

10 - 3 ( x + 7 ) = 26

<em>First Step: Distribute</em>

- 3 to ( x + 7 )

=  10 - 3 x - 21 = 26

<em>Second Step: Combine like terms</em>

10 - 21

=  - 11 - 3 x = 26

<em>Third Step: Add from both sides</em>

26 + 11

=  - 3 x = 37

<em>Fourth Step: Divide from both sides</em>

37 / - 3

<u>x = 12</u>
