Question

Write the equation of the line that passes through the points (3, 4) and (-3, -8) in point-slope form.

Answer 1

aww i lost my post!!!!

Answer 2

goodnight

Answer 3

slope is 2 via right 6, up 12

Answer 4

\[slope=m=\frac{ \Delta y}{\Delta x}=\frac{-8-4}{-3-3}=\frac{-12}{-6}=2\]

Answer 5

y=mx+b
y=2x+b
we know a point on the line (3,4)
4=2(3)+b
4=6+b
we can solve for b (the y-intercept)
4-6=b
-2=b
so we have y=2x-2

Answer 6

then use
\[y-y_1=m(x-x_1) \] with
\[m=2, x_1=3, y_1=4\]
