Answer:
Step-by-step explanation:
First , let us rewrite the given equation into y= mx+b format
.y= -x +7
Slope is -1
Slope of the line perpendicular to the given equation is -(-1) ie., 1
Let us find the y-intercept by plugging in the values of x,y and slope into the equation y= Mx +b
1 = -1 +b
2 = b
Equation of the line perpendicular to the given equation and passing through (-1,1) is
y=x +2
