Answer:
Scalene triangle
Step-by-step explanation:
Coordinates of the vertices of the triangle are,
W(-7, 1), X(0, -4) and Y(2, 3)
We will use the formula to get the distance between two points.
d = 
WX = 
= 
WY = 
= 
XY = 
= 
= 
Since, measures of all three sides of the triangle are not equal, given triangle will be a scalene triangle.
