• Positive
• Negative
• Zero
• Undefined

What is the slope-intercept form of a line?

• Ax + By = C

• y = mx + b

• y - y1 = m(x - x1)

• y = Ax + By

What is standard form of a line?

• y = mx + b

• Ax + By = C

• y - y1 = m(x - x1)

• y = Ax + By

Identify the formula used to find slope.

• $m=\frac{y_2-y_1}{x_2-x_1}$

•  $m=\frac{x_2-x_1}{y_2-y_1}$ 

•  $y=mx+b$  

•  $y_1\sim mx_1+b$  

The slope in this scenario is... and means....

• $0; how much 0 gallons of gas costs

• $3.75; the cost of gas per gallon

• $15; the cost of gas

• 4 gallons; the number of gallons

Which equation matches the graph? 

• y = 2x
• y = 1/4 x + 2
• y = 1x + 4
• y = -2x

Write the equation of the line.

• y= -1x-3
• y= -3x-1
• y=(-1/3)x-1
• y= -3x-3
