Two lines, A and B, are represented by the following equations:

2 answers:

8 0

Line A: 2x+2y=8 ⇒2y=-2x+8 ⇒ y=-x+4
Line B: x+y=3 ⇒y=-x+3

Therefore: y=y then:
-x+4=-x+3
-x+x=3-4
0≠-1 ⇒There is no solution because the lines are parallels

Answer: There is no solution

Sergeeva-Olga [200]

Answer: (-9,6)

Step-by-step explanation:

3x+2y=-15

2x=-18

First solve for x in second equation

2x=-18

2x/2=-18/2

X= -9

Now substitute your x into first equation to find y

3(-9)+2y= -15

-27+2y=-15

2y= -15+27

2y= 12

2y/2=12/2

Y= 6

Choose the equation that represents the line that passes through the point (6,-3,) and has a slope of 1/2

dezoksy [38]

Answer:

$y=\frac{1}{2}x-6$

Step-by-step explanation:

The general equation of a line: $y = ax+b$

In our case a is given

$a=\frac{1}{2}$

Now we plug in for a and we get:

$y=\frac{1}{2}*x+b$

Now we plug in our coordinates into this equation and we solve for b

$-3=\frac{1}{2}*6+b\\b = -6$

So the equation of the line is $y=\frac{1}{2}x-6$
