Sorry. It is contrary to the code of conduct to just post answers. Too many kids try to avoid learning that way.

First, determine the slope of the given line. x + 2y = 6 Solve for y to get this in slopeintercept form. Remember to switch signs when you switch sides. 2y = x + 6 Divide all terms on both sides by 2. y = 0.5 x + 3 So the slope of the given line is the coefficient of x, which is 0.5 = 1/2 The slope of a perpendicular line is the negative reciprocal of that slope, which would be 2. Use the pointslope form to build the equation with the point (4,2) y  y1 = m(x  x1), where (x1, y1) is a point on the line and m is the slope. y  2 = 2(x  4) This is an equation that satisfies the question. To get this into slopeintercept form, expand, simplify and solve for y. y = 2x  8 + 2 y = 2x  6

That is pointslope form. The given line has slope 2 so the perpendicular has slope 1/2 replace y1with 1, m with 1/2 and x1 with 4 and simplify. That will be the equation of the desired line.

and make y the subject of the formula

To simplify, distribute the 1/2 and then add 1 to both sides.
