Answer:
See attached picture.
Step-by-step explanation:
Graph the line using a y-intercept -1 and slope 1.
Graph the equation with vertex (0,0) and radius 2.
Answer with explanation:
The two system of equation , one of which is a circle and another is line
x²+y²=4
x -y=1
has either no intersection point, that is the line and circle will not intersect.
Has one point of intersection, which will be tangent to the circle.
Third , the line will cut the circle at two points,that is there are two points of intersection of line and circle.
Plotting the graph of circle and line , found that line will cut circle at two distinct points.
