Answer:
y=1/2x.
Step-by-step explanation:
First, you would like to distrubte the fraction to make it become: 1/2x+1 on the right side. Second you would like to put it in y=mx+b form. Isolate y to y=1/2x. Then, you can start on (0,0), the orgin and they go up 1 and over 2 right.

Answer:
yes, system have a solution
Step-by-step explanation:
Given data
linear equation = 6
unknown = 9
to find out
Will the system necessarily have a solution
solution
we multiply one non zero solution and we know that
A = 6 × 9 matrix
and n = 9
so dim (NulA) = 3
because we know (9-6) = 3
and rank of (A) = n - dim(NulA) = 9 - 3 = 6
so we say now here image of A i.e 6 dimensional subspace (A have 6 row)
so that Col (A) will be
so its mean Ax = b has solution when we have b
so we now say that yes, system have a solution
First, we have to make sure that the number of columns in the first matrix is equal to the number of rows in the second matrix.
Since this is true, we can continue to solve the problem.
To multiply two matrices, multiply each row element in the first matrix by each column element in the second matrix. For example:
1*2 = 2
-3*1=-3
Then we add them to get our new matrix element.
-3+2=
-1Then we move to the next column of the second matrix.
1*3=3
-3*2=-6
-6+3=
-3Then the final column of the second matrix.
1*4=4
-3*3=-9
-9+4=-5
Our matrix so far:
We do the same for the bottom row of the first matrix.
<em>First Column</em>
2*2=4
0*1=0
4+0=
4<em>Second Column
</em>2*3=6
0*2=0
6+0=
6
<em>Third Column</em>
2*4=8
0*3=0
8+0=
8Our final matrix is:
