Question

Line m has slope -2 and contains the point (3, -7). Which of the following is a point-slope equation of line m?

Answer 1

\[y - y_1 = m(x-x_1)\]

Answer 2

\[y - (-7) = -2 (x - 3)\]Solve until you get it in; y = mx + b form

Answer 3

soo how would i have too do it

Answer 4

solve for "y".

Answer 5

i really dk how to do this

Answer 6

@hoblos , please help here. i will brb.

Answer 7

the general point-slope equation of line of slope m and passing by (x1,y1) is

y-y1=m(x-x1)

here m=-2 x1=3 y1=-7

so
y-(-7) = -2(x-3)
y+7=-2(x-3)
