Answer:

-1

Step-by-step explanation:

We can use the formula to find slope

(y2-y1) / (x2-x1)

y1 is the first Y coordinate in the first pair

y2 is the second one in the first pair

X1 is the first X coordinate in the frst pair

x2 is the second one In the second pair.

so if we put it together it’d look liek this

(5- (-) 2) / (-4 - 3)

5+2 / -4 + -3

7/-7

or -1

What is the sum of 3 consecutive odd integers is -39

trapecia [35]

Answer: The three consecutive odd integers are: -15, -13, and -11 .
_______________________________________________________
Explanation:
_____________________________________________
x + (x + 2) + (x + 4) = -39 ;
_____________________________________________
in which "x" is one of the integers,
"(x + 2)" is the next consecutive odd integer;
"(x + 4)" is the third consecutive odd integer.
__________________________________________
By solving for "x", we can solve for each of three (3) consecutive odd integers.
________________________________________________________
x + (x + 2) + (x + 4) = -39 ;
_________________________________________________________
1x + 1x + 2 + 1x+ 4 = -39 ;
_____________________________________________________
3x + 6 = -39 ;
______________________________________________
Subtract "6" from EACH side of the equation:
______________________________________________
3x + 6 − 6 = -39 − 6 ;
____________________________________________________
to get: 3x = -45 ;
____________________________________________________
Divide EACH side of the equation by "3" ;
____________________________________________________
3x / 3 = -45 / 3 ;
_____________________________________________________
to get: x = -15 ;
______________________________________________________
x + 2 = -15 + 2 = -13 ;
_______________________________________________________
x + 4 = -15 + 4 = -11 .
___________________________________________________
Are: -15, -13, and -11 ; Consecutive odd integers? YES!
___________________________________________________
Does: -15 + (-13) + (-11) =? = -39 ??
_____________________________________________________
-15 − 13 − 11 = ? 39 ?? YES!
____________________________________________________
Answer: The three consecutive odd integers are: -15, -13, and -11.

Enter the slope-intercept equation of the line that has the same slope as y - 3 = (x + 3) and contains

mario62 [17]

Given:

$y-3=\frac{1}{2}(x+3)$

Point = (8, 4)

To find:

The slope-intercept form of the equation of the line.

Solution:

$$y-3=\frac{1}{2}(x+3)$

Slope of this line = $\frac{1}{2}$ .

Slope of the line is same as the slope of $y-3=\frac{1}{2}(x+3)$ .

Slope of the line (m) = $\frac{1}{2}$

General form of line:

y = mx + b

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

It contains the point (8, 4). Substitute x = 8 and y = 4 in (1).

$4=\frac{1}{2}( 8)+b$

$4=4+b$

Subtract 4 from both sides, we get

b = 0

Substitute b = 0 in (1).

Equation of the line:

$y=\frac{1}{2} x+0$

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

Complete the sentence:

$y=\frac{1}{2} x$ ; I used the general form of a line in slope-intercept form, y = mx + b. The slope, m is $\frac{1}{2}$ . Then I substituted 8 for x and 4 for y into the standard form and solved for b, which is 0.
