__ The slope of any line perpendicular to AB , where A(0, -3) and B(4, 9) are two points on the line, is m =
a.-3 b.-1/3 c.3
start wid finding the slope of AB
do u knw how to find slope of two points ?
no
u must be having slope formula in ur notes.. can u pls check if u have it ready and tell me the formula :)
what i wrote in the first post is all i got.
ok, use this formula :- slope of two points = \(\frac{y2-y1}{x2-x1}\)
using that first find the slope of AB. then u can use that value to find the slope thats perpendicular to AB.
give it a try :)
i really still dont get it :/
you wil get if u pay attention a bit
A(0, -3) and B(4, 9) x1 y1 x2 y2
just we need to plug them in the slope formula
would it be 1/3?
Answer : -1/3 you dont care how to solve...
