Answer:
y=6
Step-by-step explanation:
The equation of the line with slope 2 is y=2x+b, b is a constant which should be determined. The line passes via through points (1, 2) and (3,y)
(1, 2): 2=2+b --> b=0
So, the equation of the line is y=2x. Now, when x=3, y=6. So the line y=2x passes through points (1, 2) and (3, 6). (3,y)=(3, 6).
Answer:
c
Step-by-step explanation:
gm=cm+rg
gm-cm=rg
m(g-c)/g-c = rg/g-c
m=r g/g-c
-3m=4m-15
-3m-4m=-15
-7m=-15
-15/-7m
= -2.14
-15/-3-4= 2.14
