• slope: 5   y-intercept:  (0,3) 
• slope: 3/2   y-intercept:  (0,3) 
• slope:  4  y-intercept:  (0,3/2)
• slope: 1/5   y-intercept:  (0,5)

What is the y-intercept?

• 1/2
• 2
• 7
• 3

I paid 1000 dollars for a new I-phone 12 Pro and have to pay 20 dollars a month for cell service. Which equation will show me how much will pay in 7 months?

• y=1000x + 20

• 1000x + 20y = 7

• y= 20x + 1000

• 1000 + 12 = 20

How would the following equations look if you graphed them?

y= 1/2x - 2

y= 4x - 2

• They are parallel because they have the same slope.

• They would cross the y-axis at the same place.

• They would be perpendicular.

• They would look like a hot mess.

Solutions to linear equations are....

• ordered pairs (x,y)
• slope
• y-intercept

When graphing, one always marks FIRST

• the y-intercept on the y-axis

• the slope on the y-axis

• the y-intercept on the x-axis

• the slope on the x-axis

When graphing, one always starts counting the slope

• from the origin (0,0)

• on the y-axis

• from the y-intercept

• on the x-axis
