Hi All!(adsbygoogle = window.adsbygoogle || []).push({});

I am trying to figure out how to solve problems like the one below. Any guidence would be appreciated.

Work out the equation of the straight line through (3, -7) and (6, -16) in the form y = m x + c.

m = (-7) - (-16) = 9 = -3

__________ ___

(3) - (6) -3

m = -3

y = mx + c

-7 = (-3)(3) + c

-7 = -9 + c

c = -9 - (-7)

c = -2

y = (-3)x + -2

That is what I have done so far, am I doing it correctly ?
