Find line through (5,5) and perpendicular to 2x+3y+4=0
Solution:
Your problem `->` line through (5,5) and perpendicular to 2x+3y+4=0
When two lines are perpendicular, their slopes are opposite reciprocals of one another or the product of their slopes is -1.
We shall first find the slope of line `2x+3y+4=0`
`2x+3y+4=0`
`:. 3y=-2x-4`
`:. y=-(2x)/(3)-4/3`
`:.` Slope`=-2/3`
`:.` Slope of perpendicular line`=3/2`
The equation of a line with slope m and passing through `(x_1,y_1)` is `y-y_1=m(x-x_1)`
Putting `(5,5)` for `(x_1,y_1)` and `m=3/2,` we get
`:. y-5=3/2(x-5)`
`:. 2(y-5)=3(x-5)`
`:. 2y -10=3x -15`
`:. 3x-2y-5=0`
