Help this my FINAL EXAM 1:would it be easier to find the slope or the x intercept of line described by y=2x+3? Explain

2:when is the inequality 5x>0 true?
A-the inequality is true for all values of x
B-the inequality is only true if x is positive
C-the inequality is true only if x is 0
D- the inequality is true only if x is negative

3:The equation of line 1 is x+2y=10, and the equation of line 2 is x-4y=4. What is the point of intersection of the two lines?
A-(5,2)
B-(-5,4)
C-(8,1)
D-(8,-1)

4:the graph shows the equation 6x-3y=12 and y=2x+4. What is the solution of the graph?

5: A former raises pigs and chickens on his farm. He has a total of 37 animals and altogether his animals have 110 legs. This can be set up as a system such as that:
P+C=37
4p+2c=110

Lizzy graphed these two lines with P as c and C as y and got an intersection point at (13,24). What does that mean in the context of the problem?
A-there are 13 chickens and 24 pigs on the farm
B-there are 12 pigs and 23 chickens on the farm
C-there are 24 chickens and 23 pigs on the farm
D-there are 13 pigs and 24 chickens on the farm
