Functions Systems

Which of the following is the solution(s) to the system below? y = x² + 3x - 6 y = x² + 3

• (12, 3)

• (3, 12)

• (0, 3)

• No Solution

Don't forget DCMAM. Get the variable by itself on one side. (a)  

• H

• F

• G

• J

What can we use to find slope and y-intercept when we have a table? (a)  

• F

• G

• H

• J

The solution to this system is...

• (4, -2)

• (4, 2)

• (-2, 4) 

• (-4, -2)

Find the value of y when x = 2.

• 2

• 6

• 7

• 8

What is the solution?

• No solution

• (0, 2)

• (0, -4)

• (3, -3)

If a system of linear equations has infinitely many solutions, what does this mean about the two lines? 

• Intersecting lines

• Same line

• Parallel lines

Is this mapping a function and how can you tell?

• Yes its a function cause all the numbers have lines

• No it's not a function because there a 5 in both ovals

• No it's not a function because the x value 5 has y values of  2 & 9

• No it's not a function because the y value 5 has x values of  2 & 9

Is this table a function and how can you tell?

• Yes its a function because there are not variables for missing numbers

• No it's not a function because the y value 4 repeated

• No it isn't a function because the x value 2 is repeated

• No it's not a function because the x value 5 has y values of  10 & 12

Determine if (4, 1) is a solution for the system of equations.
y = -x + 5
y = 2x - 7

• yes

• no
