The center of a circle is at the origin on a coordinate grid. a line with a positive slope intersects the circle at (0, 7). which statement must be true? the circle has a radius greater than 7. the circle has a radius equal to 7. the slope of the line is equal to 7. the slope of the line is not equal to 7.

EDGE2020 Option B :)

Step-by-step explanation:

The correct option is 2. The circle has a radius equal to 7.

Step-by-step explanation:

It is given that center of a circle is at the origin on a coordinate grid.

The standard form of the circle is

Where (h,k) is center of the circle and r is radius.

The equation of the circle is

The line intersects the circle at (0,7) it means the point lies on the circle.

Put x=0 and y=7 in the above equation.

Therefore the radius of the circle is 7 units.

The line is passing through the point (0,7) with positive slope. Two points are required to find the slope of a line.

Since we have a single point therefore we cannot find the slope of the line. Second option is correct.
