Answer:

Explanation:
First find the rate of change [slope]:


Then plug these coordinates into the Slope-Intercept Formula instead of the Point-Slope Formula because you get it done much swiftly. It does not matter which ordered pair you choose:
−7 = −2[4] + b
−8

If you want it in Standard Form:
y = −2x + 1
+2x + 2x
_________

_______________________________________________
5 = [−2]² + b
4

y = −2x + 1
+2x + 2x
_________

** You see? I told you it did not matter which ordered pair you choose because you will always get the exact same result.
