Question 398715: i need to write an equation for the line that is perpendicular to the given line and that passes through the given point. Please and thank you
25.y=2x+7 (0,0)
26.y=x-3;(4,6)
27.y= -1/3x + 2;(,2)
28. 3x+5y=7;(-1,2)
29. -10x + 8y =3; (15, 12)
30. 4x-2y=9; (8,-2)

You can put this solution on YOUR website! i need to write an equation for the line that is perpendicular to the given line and that passes through the given point. Please and thank you
25.y=2x+7 (0,0)
slope m = 2
the perpendicular line will have slope -1/2. ( negative reciprocal)
find b from the equation y = mx +b
plug(0,0,)
0=0+b
b=0
...
so the equation will be
Check with graph
The equations below are to be solved in a similar manner
26.y=x-3;(4,6)
27.y= -1/3x + 2;(,2)
28. 3x+5y=7;(-1,2)
29. -10x + 8y =3; (15, 12)
30. 4x-2y=9; (8,-2)
