I think 1 is your answer Because 3 points will determine a plane.
4in and 29ft and 21in 9ft and 4ft and 6yd Hope this helps:) u do this b adding and subtracting like the ones here u can solve this easily by doing the functions they want u to do
Hello!

Slope-intercept form is y = mx + b where:
m = slope
b = y-intercept
Plug in the given values:
y = 2x - 4
56x² - 49x + 14 = 7(8x² - 7x +2)
_____
The greatest common factor of 56, 49, and 14 is 7.
