If the lines with those given slopes go trough 2 points then
A) is correct if the points are (6, 0) and (0, 3)
B) is correct if the points are (0, 0) and (-6, 3)
C) is correct if the points are (-6, 0) and (0, 3)
Sal: 25 +5x = 240
Divide 5 from both sides so it would be 5+ x=240/5
Subtract 5 from both sides x=48-5
X= 43
Elena: 15 + 5x=300
Divide 5 from both sides so it would be 3 +x=300/5
Subtract 15 from both sides x=60-3
X=57
So Sal jogged for 43 minutes. While Elena jogged for 57 minutes
f(x) h(x)
x | y x | y
0 | 3 -3 | -3
1 | 5 -2 | -1
2 | 7 -1 | 1
3 | 9 0 | 3
4 | 11 1 | 5
5 | 13 2 | 7
3 | 9
4 | 11
5 | 13
The lines will cross at infinite points, because they are parallel to one another. The question stated that f(x) = h(x), so the inputs and outputs will be the same for both equations.
