Explanation:
To find the slope
(
m
)
of the straight line that passes through two points
(
x
1
,
y
1
)
and
(
x
2
,
y
2
)
apply:
(
y
1
−
y
2
)
=
m
(
x
1
−
x
2
)
In this example our two points are
(
0
,
1
)
and
(
2
,
4
)
Hence:
(
1
−
4
)
=
m
(
0
−
2
)
−
3
=
−
2
m
→
m
=
3
2
The equation of a straight line in slope
(
m
)
and intercept
(
c
)
form is:
y
=
m
x
+
c
In this example:
y
=
3
2
x
+
c
Since the point
(
0
,
1
)
is on this line
→
1
=
0
+
c
Hence,
c
=
1
∴
y
=
3
2
x
+
1
is our required straight line.
Step-by-step explanation:
Answer:
x=-8
Step-by-step explanation:
1 Simplify 1/10x to x/10.
x/10 + 9/10 = 1/10
2 Join the denominators.
x+9/10 = 1/10
3 Multiply both sides by 10.
x+9 = 1/10×10
4 Cancel 10.
x+9=1
5 Subtract 9 from both sides.
x=1-9
6 Simplify 1-9 to -8.
x=-8
