Question

Find the x value for point L such that JL and KL form a 3:1 ratio.

Answer 1

Answer:

C. 2.25

Step-by-step explanation:

The following information is missing: J is at (-3, 4). K is at (4,-2).

The x value for point L such that JL and KL form a 3:1 ratio is obtained as follows:

• m/(m+n)*run + xJ

where ratio m:n givesfraction m/(m+n), run is the distance over x-axis between J and K, and xJ is the x-coordinate of J.

• ratio 3:1 means: m/(m+n) = 3/(3+1) = 3/4

• run = 4 - (-3) = 7

• xJ = -3

Replacing into the equation:

m/(m+n)*run + xJ = 3/4*7 + (-3) = 2.25
