Write an equation of the line that passes through (-2,5) and (4, -7).

Step-by-step 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.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

45
