Step-by-step explanation:
A is excluded because in the second() x² should be negative
B is excluded because if you solve it -(-x² give you + x²
C is excluded because in the second() 2x and 1 should be negative
so D is right
Since bx does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting bx from both sides.
<span>-ay=-bx+2 </span>
<span>ax+by=3 </span>
<span>Divide each term in the equation by -1a. </span>
<span>y=(bx-2)/(a) </span>
<span>ax+by=3 </span>
<span>Divide each term in the numerator by the denominator. </span>
<span>y=(bx)/(a)-(2)/(a) </span>
<span>ax+by=3 </span>
<span>The equation is not linear, so the slope does not exist. </span>
<span>No slope can be found. </span>
<span>ax+by=3 </span>
<span>Since ax does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting ax from both sides. </span>
<span>No slope can be found. </span>
<span>by=-ax+3 </span>
<span>Remove the common factors that were cancelled out. </span>
<span>No slope can be found. </span>
<span>y=-(ax)/(b)+(3)/(b) </span>
<span>Divide each term in the equation by b. </span>
<span>No slope can be found. </span>
<span>y=(-ax+3)/(b) </span>
<span>Divide each term in the numerator by the denominator. </span>
<span>No slope can be found. </span>
<span>y=-(ax)/(b)+(3)/(b) </span>
<span>The equation is not linear, so the slope does not exist. </span>
<span>No slope can be found. </span>
<span>No slope can be found. </span>
<span>Compare the slopes (m) of the two equations. </span>
<span>m1=, m2= </span>
<span>The equations are parallel because the slopes of the two lines are equal.

Answer:
1
Step-by-step explanation:
-3-2= -6
4+1=5
-2+3=1
-5+5+1=1
Y = 2x + 1
y - 1 = 2x
x = y - 1/2
