Answer:
y = 3x - 11
Step-by-step explanation:
Step 1:
y = mx + b Slope Intercept Form
Step 2:
y = 3x + b Input Slope
Step 3:
- 5 = 3 ( 2 ) + b Input x and y values
Step 4:
- 5 = 6 + b Multiply
Step 5:
- 11 = b Subtract 6 on both sides
Answer:
y = 3x - 11
Hope This Helps :)
How do you solve this system of equations using the addition method:

x
=
−
2
,
y
=

4
Explanation:
Right now, you have:
4
x
−
y
=
−
4
5
x
+
2
y
=
−
18
To make this easier, you must get rid of one variable, in this case I will remove
y
, to do this you must make the y-values in both equations the same.
To do this, I will multiply the whole of
4
x
−
y
=
−
4
by 2 to give
8
x
−
2
y
=
−
8
We now have:
8
x
−
2
y
=
−
8
5
z
+
2
y
=
−
18
All we need to do now is
(
8
x
−
2
y
+
5
x
+
2
y
)
=
(
−
18
−
8
)
≡
13
x
=
−
26
.
Divide both sides by 13 to find
x
:
13
x
=
−
26
13
x
13
=
−
26
13
x
=
−
2
Now put your value for
x
into either equation:
4
(
−
2
)
−
y
=
−
4
−
8
−
y
=
−
4
y
=
−
8
+
4
y
=
−
4
x
=
−

;
y
=

Answer:
1. 8+(30/(2+4)) = 8+(30/6) = 8+5 = 13
2. ((8+30)/2)+4 = (38/2)+4 = 19+4 = 23
Step-by-step explanation:

Recall that, to get the inverse relation of any expression, we start off by doing a quick switcharoo on the variables, then we solve for "y".
Answer:
a = -1/2
Step-by-step explanation:
- 1/4a - 4 = 7/4a - 3
- 1/4a - 7/4a = - 3 + 4
- 8/4a = 1
- a = 1 / 8/4
- a = 1 * 4/8
- a = 4/8
- a = 1/2
a = - 1/2
