Question

Determine the equation of the line, in point-slope form, that runs through points (2, -4) and (-4, -6)

A) y-4=1/3(x+2)
B) y+4=1/3x-2
C) y+4=1/3(x-2)

Answer 1

Find slope first
\[m =\frac{ (y2-y1) }{ (x2-x1)}\]

Answer 2

plug in your known points, into the slope formula.

Answer 3

that is your first step.

Answer 4

Slope is -2/-6

Answer 5

Great. Simplify that fraction now.

Answer 6

formula is y-y1=mx(x-x1)

Answer 7

When you do you have a numerator and denomerator that are both positive.

Answer 8

1/3
