Answer:
The equation is 2y = x-3
Step-by-step explanation:
Equation of WX is;
2x + y = -5
Can be written as;
y = -5 -2x
compare it with standard form
y = mx + c
where m is slope and c is intercept.
Slope of the line is thus -2
The second line is perpendicular to WX
this means that the product of their slopes is -1
Mathematically;
-2 * slope of second line = -1
Slope of second line is -1/-2 = 1/2
Now we use the point slope form to get the equation of that second line
Mathematically;
y-y1 = m(x-x1)
y-(-2) = 1/2(x-(-1))
y + 2 = 1/2(x + 1)
2(y + 2) = x + 1
2y + 4 = x + 1
2y = x + 1-4
2y = x-3
