115 on a coordinate plane, draw triangle abc with vertices
a(-1, -1), b(3, -1), and c(-1, 2). find the area of the triangle
in square units.

Plotted the triangle... I’m presuming |-| is 1cm
So to find the area u plot the coordinates on a graph then work out the length then 1/2 the base the times the height which gives u 6cm^2

You would need a laid out graph for this but could you provide a picture of just a graph? i can give stepssolve for y.subtract 4xdivide by -1 (opposites)graph slope intercept formcheck each point to see if it’s on the graph
