Linear Equation

100

Find the Y-int of       y=3x+1

Y-int:  (0,1)

200

What is the slope of a Horizontal Line

The slope is 0

300

Calculate the slope of a line that contains the points (1,2) and (2,4)

m=2

400

Find the slope of the line     2x+3y=4

m=-2/3

500

Find the Equation of a line that contains the point (1,1) and is parallel to the line  y=3x+7

y=3x-2

Quadratic Equation

100

Find the Y-int of     y=x²+3x+2

Y-int:  (0,2)

200

Determine if  y=-2x²+x-4  has a maximum or minimum point

since a=-2 the parabola opens downwards, so it has a maximum point

300

Find the X coordinate of the Vertex of  y= 7x²+14x-3

x=-1

400

How many roots does y=x²+3x-1 have?

Using the Discriminant: b²-4ac

3²-4(1)(-1)=15

since the number is positive, it has two roots

500
