Question

Find the equation in standard form which passes through (–2, –7) and (1, –1).

Answer 1

Find the slope, then use point slope form

Answer 2

y = mx +b ?

Answer 3

The slope is 2.

Answer 4

Yes, correct

Answer 5

m(x - x_1) = (y - y_1)
2(x - 1) = (y + 1)

2x - 2 = y + 1

y = 2x - 3

Answer 6

I just got that (: lol Thank you

Answer 7

No, the slope is NOT 2.

Answer 8

\[m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-7 - (-1)}{-2 - 1} = \frac{-7 + 1}{-3} = \frac{-6}{-3}=2 \]

Answer 9

The slope IS REALLY 2
