what are some ordered pairs for y=2x+10?

Question

I want to know what are some ordered pairs for y=2x+10

Answer 1

Abcde:

 

All you would really have to do in this situation is pick some values for x, substitute them into the equation for x and solve for y.

 

Example;

 

Let's take your original equation of y=2x+10 and pick values for x, I am going to choose -1, 0, and 1.

 

Next, we will plug these values in for x and solve for y as follows

 

x = -1

 

y = 2(-1) +10--Using PEMDAS, simplify by first multiplying (-1) and 2

 

y = -2 + 10==>Now combine like terms

 

y = 8==>Solution (-1, 8)

 

Therefore when I substitute (-1) in for x, I get a y value of 8 ==> (-1, 8)

 

Now let's substitute 0 in for x

 

x = 0

 

y = 2(0) + 10==>Multiply

 

y = 0 + 10==>Combine like terms

 

y = 10==> Solution (0, 10)

 

Finally, lets substitute 1 in for x

 

x = 1

 

y = 2(1) + 10==>Multiply

 

y = 2 + 10==>Combine like terms

 

y = 12==>Solution (1, 12).

 

Repeat this as many times as you wish for any given linear equation, however, it should be noted that you will only need 2 points to graph a linear equation.
