Question

if the straight line y=mx+c passes through the point (2,4) and (-3,6) then the values of m and c are

Answer 1

Substitute (2,4) in y = mx + c

4 = 2m + c

c = 4 - 2m

Substitute (-3,6 ) in y = mx +c

6 = -3m + c

c = 6 + 3m

now equate c

4 - 2m = 6 + 3m

5m = -2

m = - 2/5


c = 4- 2m = 4 -2 (-2/5) = 4 + 4/5 = 24/5


So, answer is a)

Answer 2

Answer:

m= -2/5,, c=24/5.....
