Question

Slope of the line AB is 4/3. Co-ordinates of points A and B are (x , -5) and (2 , -3) respectively. What is the value of x?

A) 1/2 B) -1/4 C) 4 D) -4

Answer 1

Answer:

x=½ is the answer (A)

Step-by-step explanation:

as we know,

(y2-y1)/(x2-x1) = slope = 4/3

(-3+5)/(2-x) = 4/3

2/(2-x)= 4/3

cross-multiply

6 = 4(2-x) = 8-4x

4x=2

x=½
