By definition, the formula for the y coordinate is given by:
![y (y1 + ry2)/(1 + r)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/r77o70v560qx5s7fxumldx2v7r2rsm71cr.png)
Where,
r: is the ratio that divides the RS line segment
y1: y coordinate of point R.
y2: y coordinate of point S.
Substituting values we have:
![(2 + ((3)/(4))7)/(1 + (3)/(4))](https://img.qammunity.org/2019/formulas/mathematics/middle-school/785zsoqoie9kvepah0b908omi1phq8xxke.png)
Rewriting we have:
Answer:
the y value for the point located 3 over 4 the distance from R to S is:
![(29)/(7)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/nqcr4bcsi8o0e38nfyde69ancz3ae78gvn.png)
