Point/slope form is:-
y - y1 = m(x - x1) where m = slope and (x1, y1) is a point on the line
In the above diagram the slope is -1 and one point on the line is (0, -2) so we have:-
y - (-2) = -1(x - 0)
y + 2 = -x
x + y + 2 = 0 is the answer
1 3/4 because you have but how many times 4 goes into 7. Then use the difference as the numerator and use 4 as the bottom
21. Smith received 60% of the votes
Murphy received 1/3 or 33%
100% - (60% + 33%) = 100 - 93 = 7%......so where is the other 7% of the votes. The vote total should equal 100%
22. Food : 500/2000 reduces to 1/4......or 25%......or 0.25
Rent : 1200/2000 reduces to 3/5....or 60% ...or 0.6
Transportation : 300/2000 reduces to 3/20...or 15%..or 0.15
23. sum of the rows:
Food + rent + trans = 1/4 + 3/5 + 3/20 = 5/20 + 12/20 + 3/20 = 20/20 = 1
Food + rent + trans = 25% + 60% + 15% = 100%
Food + rent + trans = 0.25 + 0.6 + 0.15 = 1
The sums should all equal because the percent, decimals, and fractions are all the same, just in a different form
24. 14.5% = 0.145 = 145/1000 = 29/200
14.5 = 14.5 = 14 1/2 = 29/2
14.5% is less then 1
14.5 is greater then 1
<em>so it's equal to:</em>
