Question

the following points are plotted on a coordinate plane (-1.2), (-1.7) and (4.2) if the points are connected by a straight line with shape will they form? A: an acute triangle B: a right triangle C: an obtuse triangle D:a quadrilateral

Answer 1

Did you graph it?
from the first point to the second is VERTICAL
from the first point to the third is HORIZONTAL
so those two lines are at right angles at the first point
so
what kind of triangle is it ?

Answer 2

without graphing I notice that (-1,2) and (-1,7) lie on a vertical line, and
(-1,2) and (4,2) lie in a horizontal line.

so ....

Answer 3

So what is it?
