NEED HELP ASAP PLS !!!

Answer 1

Answer:

$2x + y = 1\:or\:y = -2x + 1$

Step-by-step explanation:

First find the rate of change [slope]:

$\frac{-y_1 + y_2}{-x_1 + x_2} = m$

$\frac{-5 - 7}{2 + 4} = -\frac{12}{6} = -2$

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

$1 = b \\ \\ y = -2x + 1$

If you want it in Standard Form:

y = −2x + 1

+2x + 2x

_________

$2x + y = 1$

_______________________________________________

5 = [−2]² + b

4

$1 = b \\ \\ y = -2x + 1$

y = −2x + 1

+2x + 2x

_________

$2x + y = 1$

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

I am joyous to assist you anytime.
