The perpendicular slope is the negative reciprocal of the slope of the line it is perpendicular to. Therefore, the slope would be the negative reciprocal of -1/2 which would be 2.

From there, you plug in the coordinate into x and y and solve for b;

5 = 2 * -3 + b

5 = -6 + b

b = 11

Therefore the equation is;

y = 2x + 11

Find the difference between points M(6,16) and Z(-1,14) to the nearest tenth.

I'm not sure what you mean by difference, so I am guessing you meant to write "distance". If this is not the case, then feel free to report me. Anyway, to find the distance between two points you would use the distance formula.

Distance Formula: $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ .

Let's substitute our point coordinates into the formula. We'll substitute -1 and 6 for x_2 and x_1, and 14 and 16 for y_2 and y_1. After substituting, your formula will now look like: $d=\sqrt{(-1-6)^2+(14-16)^2}$ .
