Which equation matches the graph? (Click me to see the image)

• y = 2x

• y = 1/4 x + 2

• y = 1x + 4

• y = -2x

What is the formula for Point-Slope Form?

• y - y₁ = m(x - x₁)

• y = mx + b

• y + y₁ = m(x + x₁)

• y = mx - b

Write the equation of the line in Point-Slope form that goes through the point (10,5) and has a slope of -3

• y-5=-3(x-10)

• y=-3x+35

• y+5=-3(x+10)

• y=-3x-35

What is the slope of the equation y - 2 = -6( x + 6)

• 2

• 6

• -2

• -6

point (5, 3)
Slope  2
Write in point slope form and then convert to slope intercept form

• y = 2x - 7

• y = 2x + 3

• y  = 2x + 13

• y - 3 = 2(x - 5)

Write the equation of the line.

• y= -1x-3

• y= -3x-1

• y=-1/3x-1

• y= -3x-3

Which of the following represents the equation of the line passing through (-4, 5) PERPENDICULAR to the line y = -1/2x + 5/2?

• y = 2x + 13

• y = 2x + 5

• y = -1/2x + 3

• y = -1/4x + 11/2

What is the slope of the equation?
y = -3x + 4

• -3

• 4

• -4

• 3

Write the slope intercept form of the equation graphed.

• y = -2x + 3

• y = 1.5x + 2

• y = 2x - 3

• y = -1.5x - 2

To create an equation when given two points you will need to make a List & Spreadsheet, Data & Statistics, Menu 4,6,1. Don't forget to turn the fractions into decimals by typing the fraction and pressing CTRL Enter.
