Asked by margie

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

<b>Multiply the first equation by -2. Leave the other one as is.
-12=-4m-2b
10=4m+b
=============
Now add the two equations
-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. </b>


It would be helpful, and get you quicker answers, if you put the SUBJECT (in this case <b>math</b>) 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
