How can you tell if a point is a solution to a system

Step-by-step explanation:

I'll provide a simple example to help a little more :)

Let's say the points are 2 and 3, and the system is as follows:

y = 2x - 1

1) Plug the points into the equation (if there is more than one equation, do these steps and then repeat with the other equations)

3 = 2(2) - 1

2) Solve

3 = 4 - 1

3 = 3

If you end up getting an inequality, like 3 = 0, the points are incorrect. If you get a correct equation, the points are correct. It's that simple!

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
