Thru pt (-5,12) And perpendicular to 4x-7y=-2

Hope this helps!y-12 = (7/4)(x+5) , simplify it then put in in standard from. done.......
Let's deal with the perpendicular part first. We need to find the slope of the given equation before we can figure out what the perpendicular slope is.

4x-7y=-2
7y = 4x + 2
y = (4/7)x + 2/7

So you know that the slope is 4/7. The perpendicular slope should be the opposite inverse of 4/7, which is -7/4. That's the slope you should use in your new equation.

y = (-7/4)x + b

Now plug in your point ad solve for b.

12 = (-7/4)(-5) + b
b = 13/4

Plug that into your equation and your answer is:

y = (-7/4)x + 13/4

Hope this helps! :)

slope of line 4x-7y=-2
is
m= 4/7

slope of line parallel to this line is

m2 = 7/4

equation for the second line is

y-12 = (7/4)(x+5) , simplify it then put in in standard from. done.
