2nd 6 Weeks Test Review

Which graph best represents the equation 3x + y = + 4?

• 
• 
• 
• 

Answer explanation

On your test, you will have to graph this, it is not multiple choice. Either convert it into slope intercept form to graph OR solve for the x and y intercepts by plugging in zeros.

• The graph of f is steeper than the graph of g.

• The graph of g is steeper than the graph of f.

Answer explanation

The answer choices are worded weird here. If you know that the new graph is supposed to be less steep based on the 1/2, then you can tell that the original function f(x) is steeper.

• To create g, f is translated 3 units to the left.

• To create g, f is translated 3 units to the right.

Answer explanation

The +3 is in the parenthesis, meaning it is horizontal (left or right) and does the opposite of what you think it should.

• The x-intercept of g is 3 units to the left of the x-intercept of f.

• The x-intercept of g is 3 units to the right of the x-intercept of f.

Answer explanation

The +3 is in the parenthesis, meaning it is horizontal (left or right) and does the opposite of what you think it should.

What is the equation of the line?

• x = 1

• y = 1
• y = 1x

Answer explanation

Remember HOY VUX. This is a horizontal line, meaning it will be y=#.

What is the slope of the line.

• 0

• 1

• Undefined

Answer explanation

Remember HOY VUX. This is a horizontal line, meaning it will be have a slope of zero.

Causation or Association:

The hotter the temperature of the oven, the less time needed to cook a turkey.

• Causation

• Association

• Both

• Neither

Answer explanation

HINT: Causation is where one event is the result of the occurrence of the other event.

Which statement best represents the equation of the line shown on the grid and its relationship to the x-axis?

• The equation of the line is x=-4, and the line is parallel to the x-axis.

• The equation of the line is x=-4, and the line is perpendicular to the x-axis.

• The equation of the line is y=-4, and the line is parallel to the x-axis.

• The equation of the line is y=-4, and the line is perpendicular to the x-axis.

What is the equation in standard form of the line that passes through the point (6, -1) and is parallel to the line represented by 8x + 3y = 15?

• 8x + 3y = -45

• 8x - 3y = -51

• 8x + 3y = 45

• 8x - 3y = 51

Answer explanation

If they need to be parallel, then the left side of the equation needs to be the exact same. Then, plug in the x and y and see which one is true.

Write the equation of a line PERPENDICULAR to y = -1/3x + 5 and passes through the point (6,4)

Answer explanation

Perpendicular lines have opposite reciprocal slopes.
