A line has a y-intercept of -6 and a slope of 3/5

so equation
y = 3/5 x - 6

if x = 5, y = 3/5 (5) - 6 = 3 - 6 = - 3 

Answer:

C. (5, -3)

To solve this problem you must apply the proccedure shown below:
 The equation of the line has the following form:
 y=mx+b
 where m is the slope and b is the y-intercept
Therefore, you have:
 y=(3x/5)-6
 If x=5
 y=(3(3)/5)-6
 y=-3
 Therefore, the answer is the option C, which is: C. (5,-3)
