Answer:
B
Step-by-step explanation:
We want to find the point-slope equation of a line that passes through the points (-1, 4) and (8, -2).
Point-slope form is given by:

Where <em>m</em> is the slope and (<em>x₁, y₁</em>) is a point.
So, let's find the slope of the line first. We can use the slope formula:

We can choose (-1, 4) as our point. So, (<em>x₁, y₁</em>) = (-1, 4).
Substitute:

Simplify:

Therefore, our answer is B.

Answer:
t = 1
Step-by-step explanation:
16 - 2t = t + 9 + 4t; move numbers and t's
-16 -16 ; subtract 16 from both sides
-2t = 5t -7 ; subtract -5t from both sides
-5t -5t
--------------
-7t = -7 ; divide by -7
t = 1
