Answer:
-25/16
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-7-68)/(54-6)
m=-75/48
m=-25/16
The slope-intercept form is
y
=
m
x
+
b
y
=
m
x
+
b
, where
m
m
is the slope and
b
b
is the y-intercept.
y
=
m
x
+
b
y
=

Find the values of
m
m
and
b
b
using the form
y
=

y
=

Answer:
There will be 330 7th grade students in this middle school this year.
Step-by-step explanation:
Last year enrollment = 150 students
As the enrollment increased by 120%.
i.e.
Number of Percentage increase = 120% × 150 = 120/100 × 150
= 1.2 × 150
= 180
Thus,
Total students this year = No. of Percentage increase + Last year students
= 180+150
= 330 students
Therefore, there will be 330 7th grade students in this middle school this year.
