I need help with this question... someone please help?

Determine the equation of the line perpindicular to 4x-2y+7=0 and having the same y-intercept 2x+3y-10=0


It would be great if you can help me out in this question!

Do you know the slopes and y-intercepts of the two equations you gave?
(Hint: put them in standard form, (either y = mx + b or Ax + By = C), from the standards forms you can easily determine the slope and intercept, look in your text).

For the slope of the pendendicular line, the two lines will be related by a transformation of their slope. You can use this reference for some ideas on how to do that.

can you please work out the question for me... i do not understand what your trying to tell me? I am not very good at math either, if u are generous enough to provide the steps, and not the answers - it would help me understand..

ex. Step #1:

Forula: (y2-y1)/2+(x2-x1)/2 *(1,5) and (-1,6)

then i will work out it, then tell me how to step 2 .. this will be very useful.. thank you!!

This is another time you have asked for formulas that you can use mindlessly. It would be a lot better to try to understand what you are doing.
