Shari takes violin lessons. The equation 288x – 4y = -192 relates y, the total cost of the lessons, and x, the number of lessons. Shari incorrectly states that the slope of the line is 288. Why did Shari think that 288 was the slope? Choose one option from each drop-down menu to answer the question.

• write the equation in slope-intercept form.

• coefficient of x

• coefficient of y

• divide -192 by 4

• divide 288 by -4

• -48

• 72

• -72

• 48

• constant term

Write the standard form of the equation for the graph of this line.

• 4x + 4y = -1

• 4x + 4y = 1

• x/4 + y/4 = 1

• x + y = -4

Which equation best represents the relationship between x and y in the graph?

• y = 3x + 3

• y = 3x -1

What is true about the graph? Choose all of the correct answers.

• Slope is 10/3

• Slope is 3/10

• The cost is $6 for 20 gallons of gas

• The cost is $20 for 6 gallons of gas

What is the equation of this line?

• y = 2x +2

• y = 2x -2

• y = -x + 2

• Cannot be Determined
