0.75 times 12= 9!
Answer:
y= -x
Step-by-step explanation:
<u>Slope-intercept </u><u>form</u>
y= mx +c, where m is the slope and c is the y-intercept
![\boxed{slope = \frac{y1 - y2}{x1 - x2} }](https://tex.z-dn.net/?f=%5Cboxed%7Bslope%20%3D%20%20%5Cfrac%7By1%20-%20y2%7D%7Bx1%20-%20x2%7D%20%7D)
Slope
![= \frac{7 - ( - 6)}{ - 7 - 6}](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7B7%20-%20%28%20-%206%29%7D%7B%20-%207%20-%206%7D%20)
![= \frac{7 + 6}{ - 13}](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7B7%20%2B%206%7D%7B%20-%2013%7D%20)
![= \frac{13}{ - 13}](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7B13%7D%7B%20-%2013%7D%20)
![= - 1](https://tex.z-dn.net/?f=%20%3D%20%20-%201)
Substitute m= -1 into the equation:
y= -1x +c
y= -x +c
To find the value of c, substitute a pair of coordinates.
When x= -7, y= 7,
7= -(-7) +c
7= 7 +c
c= 7 -7
c= 0
Thus, the equation of the line is y= -x.
Answer:
The standard for of the equation would be 5x + 6y = -16
Step-by-step explanation:
To start, we simply need to solve for the constant.
y + 1 = 5/6(x - 2)
y + 1 = 5/6x - 5/3
5/6x + y + 1 = -5/3
5/6x + y = -8/3
Now we need to multiply all the numbers by the largest denominator. This will make all the numbers integers. In this case, that number would be 6.
5x + 6y = -16
X = y + 4
x + 2y = 4
y + 4 + 2y = 4
3y = 0
y = 0
x = 4
The value of y is 0 and the value of x is 4
Answer:
-66
Step-by-step explanation:
7xy + 4 for x = 5 and y = -2
7(5)(-2) + 4 = 35(-2) + 4 = -70 + 4 = -66
