Question

Find the equation for the line through (2,6) and perpendicular to y = -5/4x+1

Answer 1

Helllpppp

Answer 2

Wait for a moment. I ´m solving that. but i will give u a tip. The angular coefficient must be m1=-1/m2

Answer 3

ok thanks! Let me know what you get

Answer 4

So, we should have m1=-5/4/m2

Answer 5

yes. Now what

Answer 6

Use the formalae of general line, the equation y=ax+b. and substitute the x and y for the values taken for the pair (2,6).

Answer 7

yes, i got -5/4x+17/2 is that right?!

Answer 8

????

Answer 9

So, substituting in the equation you got 6=-8/5+b; -b=-8/5-6

Answer 10

And then we got b = 38/5

Answer 11

yes

Answer 12

Using newly the equation y=ax+b we have y=-4x/5-38/5

Answer 13

the answer similar to the in multiple choice is -4/5x+38/5....

Answer 14

Thanks.

Answer 15

Don´t i deserve a medal?
