Answer:
m is the slope because it is affected by the value of x. They are multiplied together and therefore are affected by one another.
The b is the intercept because even when the x value is 0, the value of the y-intercept exists.
x is equal to 7, you plug in the 4 as the y
Answer:
Sorry. What's the question?
Answer:
The distance from the center of the circle to the longer chord is twice smaller than the distance from the center to the shorter chord.
Step-by-step explanation:
The length of the chord AB is the same as the distance OC from the center to the cord. Let OC=2x, then CA=x. By the Pythagorean theorem, the radius r of the circle is

The length of the arc ED is 4x.
Consider right triangle EFO. In this triangle, EF=2x, EO=r, then the distance OF is

The distance from the center of the circle to the longer chord is twice smaller than the distance from the center to the shorter chord.
