Well, since it says it's congruent, it's congruent. EF overbar congruent to GH overbar.
I think the answer would be 343?
(4,4)736472i would help but i jus points to do my homework lol
Solve each equation for y and then the slope is m and y-intercept is b as in:

So, if you do that, you'll get (remember, this is <em>after</em> solving for y):
1. m = -6, b = -2
2. m = 5, b = -1
3. m = -5/3, b = 5
4. m = 0, b = -1/4
5. m = -1, b = -3
6. m = 3, b = -4
7. m = 1/2, b = -5/2
8. m = 7/2, b = 1
Hope this helps.
T=an+b
subtract an from each side
b=t-an
