Help I will give brainiest also, show work

Which equation describes a line that passes through (-6, 8) and is perpendicular to the line described by y=2x-4?

1. y=2x+20
2. y=1/2x+11
3. y=-1/2x+5
4.y=-2x-4​

Alarger number is double the sum of a smaller number. the larger number is 2 less than 3 times the smaller number. if y represents the larger number and x represents the smaller number, which equations model the situation
