Chapter 2 Review

Write the equation that best matches the graph shown.

• $y=4x$

• $y=4x-3$

• $y=\frac{4}{3}x+4$

• $y=\frac{4}{3}x-3$

Answer explanation

What is the equation of this line in slope-intercept form?

• y = 2x + 5

• y = -2x + 5

• y = -2x

• y = 5

Answer explanation

What is the equation of this line?

• 0

• undefined

• 
  

  $y=-2$
  

• $x=-2$

Answer explanation

vertical lines all start with x =
so the only answer choice it could be is x = -2

What is the slope in the picture?

• Positive
• Negative
• Zero
• Undefined

A line passes through (-4, 3) and has slope  $m\ =\ \frac{5}{4}$   Write an equation in slope intercept form.

•  $y=\frac{5}{4}x+8$  

•  $y=-\frac{5}{4}x+8$  

•  $y=8x-\frac{5}{4}$  

•  $y=\frac{3}{4}x+8$  

Write the equation of the line that passes through the point (4, -2) and has a slope of -1/2.

• 
  

  $y=-\frac{1}{2}x+3$
  

• $y=-\frac{1}{2}x$

• $y=-\frac{1}{2}x+4$

• $y=-\frac{1}{2}x-4$
