Question

A linear function y =mx+ c passes through (2,5)and(4,13) find the value of a and m

Answer 1

Answer:

The value of m= 4 and I think you meant c by a, so here the value of c= -3

Step-by-step explanation:

Just put both of those co-ordinates one at a time as,

5= m*2 + c.........(equation 1)

13= m*4 + c.......(equation 2)

Now, subtracting equation 2 by equation 1,

13= m*4 + c

-5= -m*2 - c

So, 8= m*2

Therefore, m= 4

Now put m=4 in equation 1, we get

5= 4*2 + c

Therefore, c= 5 - 8

so, c= -3

Answer 2

Answer:

c = -3 and m = 4

There is no variable like a.

Step-by-step explanation:

Put values of x and y from coordinates of the points given separately to form two equations.

Now solve the two linear equations by substitution or elimination.
