line r when plotted passes through the points (1,-3) and (5,9).When line s crosses line r it forms right angles. Which of the following must be the slope of line s

H=   2(area/a+b)h= 2(144/a+b)h= 2(144/18+18)h= 2(144/36)h= 2(4)h=8

Hi ur litt it's pretty cool that i get points for just rambdomly answering stuff

Ithink d would be correct

Magma forms by partial melting of upper mantle and crust. partial melt means that only a fraction of the available material forms a melt, and that the remainder stays solid. the partial melt rises because of its lower density and ascends through he crust. this is so conclusive mean the answer would be magma igneous rocks or balistic magma.
