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
=

Answer:
9
Step-by-step explanation:
-15 - -14y = -9
two negatives (close together) makes a positive
-15y + 14y = -9
add like terms
-1y = -9
get y alone (divide whats in front of it) and do the same on the other side
-1y/-1 = -9/-1
if you divide two negatives it makes it positive so youll get 9
Answer:1. X=2 y=4
2. X=2.5 y=3
3.x=0 y=-1
Step-by-step explanation:
1. 6x=12
x=2
replace
4+y=8
y=4
2.
8x=20
x=2.5
replace
5+3y=14
y=3
3.
-6y=6
y=-1
replace
x=0
Answer:
Step-by-step explanation:
Let one number=x
Therefore the othernumber=x+b
Since,
x+x+b=58
==>2x+b=58
==>2x=58-b
==>x=(58-b)/2
Therefore the other number is (58-b)/2 + b
