Answer:
The coordinates of the point on the directed line segment from (-4, - 7) to
(-3,1) that partitions the segment into a ratio of 2 to 3 is
or
∴ PointP( x , y ) = ( -3.6, -3.8)
Step-by-step explanation:
Let he points be,
point A( x₁ , y₁) ≡ ( -4 ,-7)
point B( x₂ , y₂) ≡ (-3 , 1)
and Point P( x , y ) be the point on the line Segment AB Divides AB internally in the ratio 2 : 3 i. e m : n
To Find:
Point P( x , y ) = ?
Solution:
IF a Point P divides Segment AB internally in the ratio m : n, then the Coordinates of Point P is given by Section Formula as
Substituting the Given values we get
∴ PointP( x , y ) = ( -3.6, -3.8)
well, let's check the graph, and use two points off of it..hmmmm it passes through (4, 0) and it also passes through (0, -4).
so, what would be the equation of a line that passes through those two points?
keeping in mind that
standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient
