Electric current flowing through wire produces heat that varies jointly as the resistance of the wire and the square of the current. The resistance of two wires are in the ratio 2:3. What current passing through the second wire will produce the same amount of heat as a current of 6 amperes
through the first wire?

c

step-by-step explanation:

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
