Check my answer?
Write the equation of the line passing through point (2,3) and is perpendicular to y=4x+7 in standard form.
I got 4x+y=11; is it right?

Best ResponseYou've already chosen the best response.1so m1 * m2 = 1 m1 = 4, m2= ?

Best ResponseYou've already chosen the best response.1no, slope of perpendicular line will be negative *reciprocal*

Best ResponseYou've already chosen the best response.1so m1*m2 = 1 4m2=1 m2 = 1/4 ok ?

Best ResponseYou've already chosen the best response.1so now u have slope of required line and a point on it, which equation will u use ?

Best ResponseYou've already chosen the best response.1(1/4)(2) = +2/4 = +0.5

Best ResponseYou've already chosen the best response.0oh wait.. y+3 = 1/4x  0.5 then would you add 1/4x to the left side? since I have to write it in standard form? ax+by=c?

Best ResponseYou've already chosen the best response.11) its y+3 = 1/4x + 0.5 2) yes., add 1/4 x , not 1/4 x

Best ResponseYou've already chosen the best response.0ohk so .. 1/4x+y+3=0.5 then add subtract 3 on both sides?

hartnn

Best ResponseYou've already chosen the best response.1or u could first multiply by 4 on both sides

Best ResponseYou've already chosen the best response.0oh yeah.. sorry.. and oh ohk if i did that it would be x+y=2

hartnn

Best ResponseYou've already chosen the best response.1let me show you steps: y+3 = 1/4x + 0.5 y+1/4 x +3= 0.5 multiplying 4 on both sides 4y+ x + 12 = 2 now can u solve ahead

hartnn

Best ResponseYou've already chosen the best response.1you will subtract 12 from both sides, right ?
