If the y-intercepts are the same, then the two linear have the same y-intercept as a solution. That is one common solution for both expressions. The two expressions intersect at that point. Since the slopes are different, there are no more common solutions since if two different lines intersect, they intersect at exactly one point and no more.
Answer: 1 intersection
Answer:

Step-by-step explanation:

Y is 6 and x is 2 I have shown my work in the picture pls ask any questions
Answer:
x = 9
Step-by-step explanation:
3x - 7 = 20
3x = 20 + 7
3x = 27
x = 9
I’m a bit rusty so take my answer with a grain of salt but I believe the equation for a circle in the coordinate plane is as follows
(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the vertex
So applying the equation we get the fourth or final answer at the bottom or
(x+1)^2 + (y-2)^2 = 64
