Not sure on a few of my answers, can you help?
1. Find the slope and y intercept : f(x)=5x7
slope = 5
intercept = (0,7). Is this right?
1/2x=5/6 my answer was 5/3 was this right?
If I have these two sets of coordinate (4,0) and (0,2) will my slope be 1/2? Same question as above with different coordinates: (0,3) and (5,3) m=6/5 am I right?

1. Correct
1/2x=5/6
x = 5/3
If that is the equation of a line, though, the slope is undefined because it is a vertical line.
Check your signs on the first coordinate problem. The second is correct.

Confused one said all were right, but the other said the first coordinates had a problem with the sign, only one is negative , so would't the answer be negative,or is it infact right? I redid it and came up with the same answer... what is wrong with that one?
