Question

MEDAL AND FANN!!!!!
20. What is an equation for the line that passes through points (-1,-4) and (1,4)? Write the equation in slope-intercept form.

Answer 1

The general formula of a line is y=mx+n
Now, lets put the points so that they satisfy this equation
For (-1,-4):
-4=-m+n call this (1)
For (1,4):
4=m+n call this (2)
Now lets add (1) and (2) we get;
0=2n then n=0
Now put n=0 into (1)
-4=-m then m=4
Thus our line's equation is
y=4x

Answer 2

awesome is that all?

Answer 3

Yes, that's it.

Answer 4
