Answer:
slope = 3. The line crosses through many points, one of which is (0,4)
Step-by-step explanation:
y = 3x + 4
Answer:
y = 
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 7 when x = 3
k =
=
, thus
y =
x ← equation of variation
When x = 7, then
y =
× 7 =
