Answer:
y=1.3 x - 0.21
Step-by-step explanation:
![y = (slope) \times x + (constant)](https://tex.z-dn.net/?f=y%20%3D%20%28slope%29%20%5Ctimes%20x%20%2B%20%28constant%29)
set (-2.3,-3.2) in above
![- 3.2 = 1.3 \times ( - 2.3) + c](https://tex.z-dn.net/?f=%20-%203.2%20%3D%201.3%20%5Ctimes%20%28%20-%202.3%29%20%2B%20c)
then c=-0.21
