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
Slope
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.
Step-by-step explanation:
the first option is the correct answer.
