Answer:
y=3x+2
Step-by-step explanation:
y is going up by 3 as x goes up by 1 so slope=3/1=3.
We can use this pattern to determine what will happen at x=0 (the y-intercept). 5-3=2 so the y-intercept is 2.
Slope-intercept form is y=mx+b where m is slope and b is y-intercept.
The equation is y=3x+2.
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
+
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
(
2
)
right
=
−
6
+
4
=
−
2
=
left
⇒
point of intersection
=
(
3
,
−
2
)
Answer:
the answer is 44 because when you subtract with questions like these always subtract with 180
Given expression is
So we can write it in verbal expression as one eight of a number.
