Question

Which is a point that will be on the line that is perpendicular to AB through point P?

Answer 1

We have to calculate the equation of the line. It would be

`m=(3-1)/(-2-(-2))=(1)/(2)`

Since it is needed to obtain a point on the perpendicular line, we must calculate the slope of the perpendicular line

`m1\cdot m2\text{ = -1 so m2=-2}`

Then as we know the intercept on y is 2 we know b in the equation y=mx+b

After this, we have the equation y=-2x+2

The point that suits for that equation is A (1,0)
