Which of the following is a point slope equation of a line that passes through the points (10,5) and (4,-7)?
2 answers:
Answer:
B) y - 5 = 2(x - 10)
Step-by-step explanation:
Slop = (5+7)/(10-4) = 12/6 = 2
Point slope form:
y - 5 = 2(x - 10)
or
y + 7 = 2(x - 4)
For this case we have that the point slope equation of a line is given by:

Where "m" is the slope and
is a point belonging to the line.
Then, we find the slope, for this we need two points:

We build the equation by choosing any of the points:
