Question

The equation of the line that passes through (2, 6) and (3, 12) in point slope form is:

Answer 1

do you know how to find slope?

Answer 2

no

Answer 3

slope = change in y / change in x

aka,
\[slope = \frac{y_2 - y_1}{x_2 - x_1}\]

Answer 4

so 6?

Answer 5

you have to sets of coordinates, each one is (x, y). you can use those to find the slope

Answer 6

yep!

Answer 7

do you know what point-slope form is?

Answer 8

y1+b(x-x1)?

Answer 9

right again! but you're missing the crucial point that makes this an actual equation: the equals sign:

y = y1 + b(x - x1)

Answer 10

so b = slope
and you know a set of coordinates you can use for (x1, y1)

Answer 11

thanks
