Aline passes through the point (–7, 5) and has a slope of 1/2. which is another point that the line passes through? (–13, 9) (–9, 13) (9, 13) (13, 9)

Selection C is appropriate.

_____
The change in x for the offered points is -6, -2, 16, 20, so the slope of 1/2 will make the change in y be -3, -1, 8, 10. When added to 5, these values are 2, 4, 13, 15. Only 13 matches the second coordinate of the given answer, so only (9, 13) will be a point on the line.

No a triangle cannot be formed because when you add the two smallest number together (which would be 11) the have to be bigger than the number it is "against" ( which would be 12)
