Answer:
(-3,-2)
Step-by-step explanation:
Rewrite first equation in slope-intercept form ( y = mx + b)
2x -y + 4 = 0
-y = -2x - 4
y = 2x + 4
Now rewrite second equation in slope intercept form
y = -x -5
Graph both equations on a calculator and you see that they intersect at (-3,-2)
(-4, 19) (x_1, y_1)
(-2, 16) (x_2, y_2)
(16-19)/(-2+4)= -3/2
the slope is -3/2
Answer:
43.98
Step-by-step explanation:
Using the formulas
C=2πr
