Answer:
[tex]\displaystyle 6x - y = -15, -6x + y = 15, or\:y = 6x + 15[/tex]
Step-by-step explanation:
First, find the rate of change [slope]:
[tex]\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{0 - 12}{0 - 2} = \frac{-12}{-2} = 6[/tex]
Then plug [−1, 9] into the Slope-Intercept Formula instead of the Point-Slope Formula because you get it done much more swiftly:
9 = 6[−1] + b
−6
[tex]\displaystyle 15 = b \\ \\ y = 6x + 15[/tex]
If you want it in Standard Form:
y = 6x + 15
- 6x - 6x
__________
[tex]\displaystyle -6x + y = 15\:OR\:6x - y = -15[/tex]
