Question

Find the equation of the line in slope-intercept form for the line through (3, -2) with slope m=4/5

Answer 1

It is known that:
\[y = \frac{4}{5}x + c\]and
\[\frac{4}{5}(3) + c = -2\]so
\[c = -\frac{22}{5}\]therefore
\[y = \frac{4}{5}x - \frac{22}{5}\]Alternatively:
\[y = \frac{1}{5}(4x - 22)\]

Answer 2

alright and if i wrote it with the 1/5 distributed out would that still count as point intercept form?

Answer 3

y= mx+b ===> y=(4/5)x -2

Answer 4

Yes you have to distribute it to get a finalaized equation.

Answer 5

*finalized

Answer 6

ok thanks!

Answer 7

Anytime =)
