A. Not equilateral because not all sides are the same B. Not obtuse because no angles are more than 90 degrees. C. Not acute because not all 3 angles in the triangle are less than 90 degrees D. Yes it's a right triangle because one angle is 90 degrees (the square on the triangle shows it's 90 degrees) E. Yes it's isosceles because two sides are the same. F. No it's not scalene because scalene means all sides are unequal, but the picture shows two sides are equal.
The answer is no/false, as long as all the dots in the scatter plot follow the generic pattern of the line, it is fine. The line does not need to touch the dots.
