Question

Which equation is in point slope form?
Point (7,4) Slope 6

a. y-7=6(x+4)
b.y-4=6(x-7)
c. y-4=6(x+7)
d.y+4=6(x-7)

Please help!!!!

Answer 1

Hello @buggie2323 and Welcome to OpenStudy! :)

point slope form is: \(y - k = m(x-h)\)
where we are given a point \((h,~k)\)
and the slope \(m\)

Answer 2

In this case,

the point = \((h,~k) = (7,~4)\)
so we can plug in \(7\) for \(h\)
and \(4\) for \(k\)

also, we were given slope = \(6\) = \(m\)
so we can plug in \(6\) for \(m\)

all into the equation \(y - k = m(x - h)\)
^4 ^6 ^7

and just remember to keep the minuses I gave (don't change them)


That should get you to your answer :)
