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.
11 x 11= 121
7 x 2= 14
11 x 5= 55
11 x 6= 66
11 x 3= 33
12 x 6= 72
8 x 8= 64
7 x 6= 42
10 x 12= 120
3 x 6= 18
12 x 8= 96
11 x 8= 88
1 x 5= 5
