Which values of m and b will create a system of equations with no solution? Select two options. y = mx + b y = –2x + A
Answers
Answer:
(I can not see the options, so I will answer in a general way)
When we have a system of linear equations:
y = a*x + b
y = c*x + d
We have 3 possible options:
One solution: This happens when the lines intersect only one time, and the solution of the system is the point where the lines intersect.
No solutions: This happens when the lines do not intersect, is the case for parallel lines (lines with the same slope but different y-intercept)
Infinite solutions: This happens when the lines do intersect at infinite points, is the case for two equal lines (so both equations represent the same line)
Now we have the system:
y = m*x + b
y = -2*x + A
We want to find values of m and b, such that this system has no solutions.
Then we know that the lines must be parallel, again, the lines must have the same slope but different y-intercept.
Then we can use:
m = -2, b = A + 1
we will get:
y = -2*x + (A + 1)
y = -2*x + A
This system has no solutions.
Other pair can be:
m = -2, b = A + 3
we will get
y = -2*x + (A + 3)
y = -2*x + A
This system has no solutions.

What is X and Y
Answers
Answer:
x = 5
y = 2
Step-by-step explanation:
In this question, you will have to use one of the equations to find the value of x in terms of y and substitute it in the other equation or vice versa.
y = 2x - 8
x - y = 3
Use the second equation to find the value of x in terms of y.
x - y = 3
x = y + 3
Now that we found that, we can substitute it in the other equation.
y = 2 (y + 3) - 8
y = 2y + 6 -8
y = 2y -2
y + 2 = 2y
y = 2
Now that we got y we can substitute the value in any of the equations to find x.
x - 2 = 3
x = 5
x-y=3
x=y+3
y=2x-8
y=2(y+3)-8
y=2y+6-8
-y=-2
y=2
Plug this back into the second equation to solve for x:
x-y=3
x-2=3
x=5
So x=5 and y=2 is the answer.
