The slope-intercept form is
y
=
m
x
+
b
, where
m
is the slope and
b
is the y-intercept.
y
=
m
x
+
b
Find the values of
m
and
b
using the form
y
=

The slope of the line is the value of
m
, and the y-intercept is the value of
b
.

So this problem just wants us to find 2/3 of 7/8
'of' means multiply
so 2/3 of 7/8 just means 2/3 times 7/8
remember
![\frac{a}{b}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7Bb%7D)
times
![\frac{c}{d}](https://tex.z-dn.net/?f=%5Cfrac%7Bc%7D%7Bd%7D)
equals
![\frac{ac}{bd}](https://tex.z-dn.net/?f=%5Cfrac%7Bac%7D%7Bbd%7D)
so
![\frac{2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D)
times
![\frac{7}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B8%7D)
equals
![\frac{(2)(7)}{(3)(8)}=\frac{14}{24}=\frac{7}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B%282%29%287%29%7D%7B%283%29%288%29%7D%3D%5Cfrac%7B14%7D%7B24%7D%3D%5Cfrac%7B7%7D%7B12%7D)
