Coordinate Algebra Unit 3 EOC Review

Consider the equations $y=2x-3$ and  $y=-x+6$ and their tables. 

• (1, -1)

• (1, 5)

• (3, 3)

• No ordered pair satisfies both equations. 

Two lines are graphed on the coordinate plane.

Which point appears to be a solution of the equations of both lines?

• (1, 3)

• (3, 1)

• (3, 3)

• (1, 1)

Based on tables, at what point do the lines $y=-x+5$ and  $y=2x-1$  intersect?

• (1, 1)

• (3, 5)

• (2, 3)

• (3, 2)

Given $f\left(x\right)=2x-1$ , find  $f\left(7\right)$ .

• 13

• 15

• 6

• 10

If $f\left(12\right)=4\left(12\right)-20$ , which function gives f(x)?

•  $f\left(x\right)=4x$  

•  $f\left(x\right)=12x$  

•  $f\left(x\right)=4x-20$  

•  $f\left(x\right)=12x-20$  

Identify the function rule based on the table.

• $f\left(x\right)=x-2$

• $f\left(x\right)=2x+1$

• $f\left(x\right)=2x+5$

• $f\left(x\right)=3x+5$

Consider the sequence 3, 6, 9, 12, 15, ...
Fifth term  $a_5$ in the above sequence is 15. Identify the recursive formula to find sixth term in the sequence. 

•  $a_6=a_5-3$  

•  $a_6=a_5+3$  

•  $a_6=a_5+15$  

•  $a_6=a_5-15$  

Which function represents the sequence given in the table?

• $a_n=a_{n-1}+1$

• $a_n=a_{n-1}+2$

• $a_n=2a_{n-1}-1$

• $a_n=2a_{n-1}-3$
