Answer:
"A car travels a distance of d km in t hours. The formula that relates d to t is d = kt. What kind of variation is it?"
a. direct
b. inverse
c. joint
d. combine
Remember:
Direct Variation is a relationship between two variables, x, and y, that can be written as y = kx where k ≠ 0. It means that as x increases, y increases, and as x decreases, y decreases.
y = kx
“y varies directly as x”
“y is directly proportional to x”
“y is proportional to x”
*k represents the constant of variation (which relates the two variables)
For finding the k(constant), use this formula:
[tex]k=\frac{y}{x}[/tex]
