y =____x + ____

help? will fan and medal :)

Answer 1

@iGreen can you help?

Answer 2

Okay, first we can find the slope..

\(m = \dfrac{y_2-y_1}{x_2-x_1}\)

\(m = \dfrac{-6+2}{2-1}\)

Can you solve that?

Answer 3

-4\[\frac{ -4 }{ 1 }\]

Answer 4

Yes, now we can plug this slope and one of the points into point-slope form then simplify to get it in slope-intercept form.

\(y + 2 = -4(x - 1)\)

Distribute -4 into the parenthesis:

\(y + 2 = -4x + 4\)

Now subtract 2 to both sides, what do you get?

Answer 5

y= -4x + 2?
