Just in case you yet need understanding or the solution...
Using the coordinates (-2,3) and (0,1) you can find the slope
slope = %281-3%29%2F0-%28-2%29%29+=+%28-2%29%2F%282%29
The slope is -%282%2F2%29
...
y=mx+b
Using the coordinate (-2,3), plug in x and y to solve for b
3 = -%282%2Fcross%282%29%29%2Across%28-2%29 + b
3 = 2 + b
b = 3-2 = 1
...
Therefore, the linear equation is
y = -3%2F2x + 1
..
Confirm this using the other coordinate (0,1)
1 = %28-3%2F2%29%2A0 + b
b = 1
