Answer:
slope=3,y-intercept=6
Step-by-step explanation:
Slope is the rate of change so It is an independent variable and has an x at the end
The y-intercept is the initial value which is technically the start off and the number 6 seems to be a dependent variable.
Answer:
400
Step-by-step explanation:
first work out the radius of priya's circle with the equation a =



we know the diameter of a circle is 2 times the radius so the diameter of priya's circle is 2x
this means that if the diameter of dan's circle is 4 times bigger it must be
8x
to find the radius of dan's circle we divide the diameter by to 2 to give
4x 
then use the a=
equation again

which equals 400
