Substitute the 1st equation in the 2nd, we get:
3x + 2(-3 + 2x) = 2
3x -6 +4x = 2
7x = 8
x = 8/7
Replace x = 8/7 in equation 1,
y = -3 + 2(8/7) = -3 +16/7 = -5/7
To write The equation of a line through the two points you would first find the slope. (y2-y2)/(x2-x1)
(-5-2)/(-3-0); -7/-3= 7/3
Now use the equation y=mx+b to find b.
2= (7/3)(0) + b
2 = b
y = 7/3x + 2
The positive x axis in polar coordinates is called a pole
Answer:
A. x-9 and x+9 because these are perfect squares. 9 times -9 is -81. x times x is x^2. 9 + -9 is 0
