Task 2-Graphing Parabolas and Lines

Which equation matches the table? Hint: Plug in x= -3 into each equation and see which one gives you y=9

• y = 3x

• y = x + 12

• y = -3x

• y = 2x

Which equation matches the table?Hint: Plug in x= 2 into each equation and see which one gives you y=6

• y = x

• y = 5x

• y = x - 4

• y = x + 4

Given the equation y=3x², if I was building a table and plugged in x=3, y= (a)  

Below is a table represented in the image. Which GRAPH represents these points? Hint: points are plotted as (x, y)
_______________________
 $x\longrightarrow\left|\ 4\ \right|\ 6\ \left|\ 8\ \right|\ 10\$  
 $y\longrightarrow\left|\ 2\ \right|\ 3\ \left|\ 4\ \right|\ 5\$
