# help!

Can you please give me one of them so I cansolve for the other one?PLease!

The general formula for a straight line is y = mx + b.
Just plug the points into the equation to arrive at two equations.
6=2m+b
10=4m+b
you have two equations and two unknowns. Solve them simultaneously to obtain an answer for b

Multiply the first equation by -2. Leave the other one as is.
-12=-4m-2b
10=4m+b
=============
-2 = 0m -b or
-2 = -b
and b = 2
Check my arithmetic. Now plug b into one of the equations to solve for m, then plug those two values into your original equation to see if it is satisfied. If so, then 2 is the answer you need.

It would be helpful, and get you quicker answers, if you put the SUBJECT (in this case math) in the SUBJECT line.

Thanks.

What would be the missing piece of information given the following information:

Find the equation of the line that passes through the points (2, 6) and (4, 10).

y = 2x + ?

4

2

7

5
