Quiz 3 Review Algebra 2

Which equation best represents the line on the graph?

• y= 1/2x
• y= -1/2x
• y = 2x
• y = -2x

Give the equation for the graph

• y = 5x - 3
• y = 4x + 2
• y =-2x + 5
• y = - 2x + 4

Given the equation y = 2x+3, what is the slope?

• 2
• x
• 3
• IDK

What is the y-intercept of this graph?

• (0,1)
• (0,-2)
• (0,0)
• (0,3)

Write the equation in point-slope form of the line that passes through the given point and has the given slope.
(4, -7); m = -1/4

• y + 7 = -1/4(x - 4)
• y - 4 = -1/4(x + 7)
• y + 7 = 4(x - 4)
• y - 7 = -1/4(x - 4)

What is the equation of the line y + 5 = -3(x - 6) in slope intercept form?

• y = -3x - 23

• y = -3x -13

• y = -3x - 11

• y = -3x+13

Which inequality describes this graph...

• y < 3x - 2

• y > 3x + 2

• y < 3x + 2

• y > 3x -2

This is a graph of which inequality?

• y > 4x - 2

• y > -2x + 4

• y < -2x

• y < 4X - 2

Determine whether point A is a solution to the linear inequality that is shown.

• Yes

• No

• Sometimes

How can I tell if an inequality will have a solid line?

• It has an equal sign.
• The symbol is greater than.
• The symbol has "or equal to."
• You just guess.
