A line is perpendicular to y=-2x+5 and intersects the point (-4,2) what is the equation of this perpendicular line

2y - x = 8  

Step-by-step explanation:

First get the slope of the line given

y=-2x+5

From the line, slope m = -2

The slope of the required line M = -1/-2 = 1/2

Substitute the point (-4, 2) and m = 1/2 into the point slope equation;

y - y0 = m(x-x0)

y - 2 = 1/2(x+4)

2(y-2) = x+ 4

2y - 4  = x+4

2y - x = 4+4

2y - x = 8

Hence the equation of this perpendicular line is 2y - x = 8  

the discriminant is 64 + 4*1*12 = 112

this is prime.
