The graph shows two lines, A and B. A coordinate plane is shown. Two lines are graphed. Line A has the equation y equals x minus 1. Line B has equation y equals negative 3 x plus 7.

Based on the graph, which statement is correct about the solution to the system of equations for lines A and B?

(1, 2) is the solution to both lines A and B.
(−1, 0) is the solution to line A but not to line B.
(3, −2) is the solution to line A but not to line B.
(2, 1) is the solution to both lines A and B.

D

Step-by-step explanation:

(2, 1) is the solution to both lines A and B.

the answer is D i took the test and got it correct

Step-by-step explanation:

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.  

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
