Answer:
(-4,-8)
Explanation:
Given is a picture with a point R and a line PQ
We have to find the point out of the 4 options lying on the perpendicular line to PQ through R
R is the point (4,2)
P is (-6,4) and Q is (4,-4)
Slope of PQ =
![(-4-4)/(4+6) =-0.8](https://img.qammunity.org/2019/formulas/mathematics/middle-school/opnsvgdsno9irent85cghppcxyno2uui52.png)
Slope of perpendicular line would be =
![(1)/(-0.8) =-1.25](https://img.qammunity.org/2019/formulas/mathematics/middle-school/nk8qdnikjb1qb2chcpd1jfj1io6q4yn6l0.png)
Equation of the line through R with slope -1.25 is
![y-2=1.25(x-4)\\y =1.25x-3](https://img.qammunity.org/2019/formulas/mathematics/middle-school/eg1okdg65k9r2blx2ky5ze3l2vekqta3i6.png)
Out of the four options,
only (-4,-8) satisfies
because
![-8 =-1.25(-4)-3](https://img.qammunity.org/2019/formulas/mathematics/middle-school/lpyanri6r0i127nduyvpuqxtg4smbc9r2i.png)
so answer is (-4,-8)
