Answer:
Step-by-step explanation:
First find the <em>rate of change</em> [<em>slope</em>]:
Then plug these coordinates into the Slope-Intercept Formula instead of the <em>Point-Slope Formula</em> because you get it done much swiftly. It does not matter which ordered pair you choose:
15 = −1⅕[−10] + b
12
If you want it in <em>Standard Form</em>:
y = −1⅕x + 3
+1⅕x + 1⅕x
______________
[We do not want fractions in our Standard Equation, so multiply by the denominator to get rid of it.]
5[1⅕x + y = 3]
_______________________________________________
−3 = −1⅕[5] + b
−6
y = −1⅕x + 3
+1⅕x + 1⅕x
______________
[We do not want fractions in our Standard Equation, so multiply by the denominator to get rid of it.]
5[1⅕x + y = 3]
** You see? I told you it did not matter which ordered pair you choose because you will always get the exact same result.
