Answer

y=12x4 is the equation of the line.

Steps

Step 1 :The slope of the given line is -2.

Step 2 :The slope of a line perpendicular to this line would be the negative reciprocal of -2, which is 1/2.

Step 3 :The equation of a line is given by y=mx+c, where m is the slope and c is the y-intercept.

Step 4 :We know the slope (m) and a point on the line (4,-2), so we can substitute these values into the equation to find the y-intercept (c).

Step 5 :After substituting, we get m = 0.5 and c = -4.0.

Step 6 :y=12x4 is the equation of the line.
