Half of the distance from one side, through the middle, to the other side.
circumference: 3.14*radius*2
I’m fairly sure it is the last one. But the pictures are hard to see. 3/2 is the slope and -1 is the y intercept. Find the point at (0,-1) , the y intercept. Then go up 3 and over 2 to find the next point
Answer:
x = 2, y = -1.
Step-by-step explanation:
2x - 5y = 9
3x + 4y = 2
Multiply first equation by -3 and the second by 2:
-6x + 15y = -27
6x + 8y = 4 Adding the 2 equations:
23y = -23
y = -1.
Now substitute this value for y in the first equation:
2x - 5(-1) = 9
2x = 9 +5(-1)
2x = 9 - 5
2x = 4
x = 2.
b = - 4
slope m = (0 + 4)/(4 - 0) = 4/4 = 1
equation
y = x - 4
