Answer:
Step-by-step explanation:
Scale= 1:1,000,000
Scaled distance = 1.8 dm
Actual distance = 1.8*1,000,000 = 1,800,000 dm
Y=2x+6.
The equation of a line is y=mx+b where m is the slope and b is the y-intercept.
Therefore, the slope is 2
Vertical stretch means the graph stretches upward, rising more rapidly than the original, the graph is steeper than the original.
Answer (x,y) (3, -2)
Explanation:
using the
substitution method
y
=
x
−
5
→
(
1
)
y
=
−
2
x
+
4
→
(
2
)
since both equations are expressed in terms of x we
can equate them
⇒
x
−
5
=
−
2
x
+
4
add 2x to both sides
2
x
+
x
−
5
=

2
x
+
4
⇒
3
x
−
5
=
4
add 5 from both sides
3
x
+
5
−
5
=
4
+
5
⇒
3
x
=
9
divide both sides by 3
3
x
3
=
9
3
⇒
x
=
3
substitute this value in
(
1
)
y
=
3
−
5
=
−
2
As a check
substitute these values into

Answer:
Slope = -8.000/2.000 = -4.000
x-intercept = -31/4 = -7.75000
y-intercept = -31/1 = -31.00000
Step-by-step explanation:
1: Graph of a Straight Line
2: Calculate the Y-Intercept
3: Calculate the X-Intercept
4: Calculate the Slope
5: Geometric figure: Straight Line
Answer: Slope = -8.000/2.000 = -4.000
Hope this helps.
