Question

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

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

m = ?

a. 2

b.6

c. 1

d. 9

I think it is c.


Remeber the definition of a slope. It is the change in y divided by the change in x. You have 2 points...the point (2,6), and the point (4,10). In the first point, the y value is 6, and in the second point, the y value is 10. So, how much has y changed? And then do the same for x. Then figure out the slope!


is the formula:y2-y1/x2-x1


Yes!!!
That's right...


Now can you help me w/ my other problem?


which one?


the one above this one


The question above this one is the same question...it's repeated.


No the one above that one!


Ok...see my response to above!


y = 2x + ?

You know it passes through (2,6), so x is 2 and y is 6. Just substitute those in the equation:

6 = 2(2) + ?
