Answer: i think A
Step-by-step explanation:
Answer:
Option 4: (x+1)^2+(y-1)^2 = 16
Step-by-step explanation:
The radius of the given circle in attached picture is: 4 units
The center is denoted by (h,k) = (-1,1)
So,
The standard form of equation with center at (h,k) and radius r
(x-h)^2 + (y-k)^2 = r^2
Putting the values
(x-(-1))^2 + (y-1)^2 = 4^2
(x+1)^2+(y-1)^2 = 16
Hence option number 4 is correct ..
false, it is an example of a rational fraction
Answer: Graph D (bottom right corner)
======================================================
Explanation:
The equation y = 3x+3 is in slope intercept form y = mx+b
m = 3 = slope
b = 3 = y intercept
In this case, both the slope and y intercept are the same (though in general they tend not to be).
The positive slope value means the line goes uphill as you move from left to right. The positive y intercept means the diagonal line crosses the y axis somewhere above the horizontal x axis. Specifically, it crosses the y axis at y = 3
Graph D is the only graph that has such a line on it. Graphs A, B and C have the positive slope line where they have a negative y intercept, so we can rule them out.
You can use graphing tools such as Desmos or Geogebra to help confirm this answer. You could also make a table of values, and plot each point, to form the lines. Two points is the minimum amount needed to form any line.
