Question

If the straight line y=mx+c passes through the point (3, -4) and(-1, 2) then the value of m is a) -2/3 b) -3/2 c) 3/2 d) 2/3​

Answer 1

Equation of line: y = mx + c

Since, it passes through the two given points, the points should satisfy the equation.

=> At (3, -4): -4 = 3m + c ..........(a)

=> At (-1, 2): 2 = -m + c ............(b)

Subtract (b) from (a),

=> -4 - 2 = 3m + m + c - c

=> -6 = 4m

=> m = -6/4

=> m = -3/2

Hence, answer is-» option(b) -3/2

Answer 2

Answer:

option b ) -3/2
