Answer:
y=2x
Step-by-step explanation:
y=mx+b
m=(6-4)/(3-2)=2
b=y-mx
b=4-(2)(2)
b=4-4
b=0
Answer:
Step-by-step explanation:
we know that
The general form of the equation of a circle is
where D, E, F are constants
step 1
Find the radius of the circle
Remember that the distance from the center to any point on the circle is equal to the radius
so
the formula to calculate the distance between two points is equal to
substitute the values
step 2
Find the equation of the circle in standard form
In this problem we have
center ( -2,1)
radius r=2 units
substitute
Step 3
Convert to general form
Answer:
its 1 because -x(-1) raised to the 10 is -1 so raised to the 2 is 1
