The slope of line perpendicular to the line with slope m is -1/m.
The line y=2/5 x+2 is in the form of the equation y=mx+c.
So, comparing equations, we get
So, the slope of a line perpendicular to the line y= 2/5 x+2 is
The slope intercept form for a line passing through the point (x1,y1) and having slope m1 is
The point given is
Also the slope for the line is -5/2 as obtained above. So
The equation is 5x+2y=6.
