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. Shari thought that the ​ (a)   was the slope. She forgot to ​ (b)   . The correct slope is ​ ​ (c)   .

• 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

Slope is know as

rise/______

• run

• fall

• none

• rise

A line passes through the point (5, -5) and has a slope of 0.

The x-value of the point is ​ (a)   . The y-value of the point is ​ (b)   . The slope of 0 means that the line is ​ (c)  

​

• 5

• -5

• horizontal

• vertical

The 'run' in rise/run tells us which directions to go on the x-axis?

• up and down

• diagonal

• left and right

Slope is know as

• rise/run

• rise * run

• none

• run/rise
