Graphing

100

Graph the coordinate

( 2, -1)

Count 2 right and down 1

200

Graph the coordinate

( 0, 3)

Up 3 

300

What is the slope of the equation

y = 1/2 x + 7

1/2

400

Graph the equation 

y = 2x + 1

(remember y = mx + b)

m is the slope / b is the y-intercept

first point at ( 0, 1) then count up 2 and right 1

500

Graph the following equation

y = - x 

Start at (0, 0) and count down 1 then right 1

Do you know any Geometry?

100

Draw a right angle

two rays or lines forming a 90-degree angle

200

How many degrees are in a circle?

360 Degrees

300

How many degrees are in a Triangle?

180 degrees

400

Draw a pair of parallel lines and a pair of perpendicular lines

Parallel lines = two lines that never intersect (in the same plane)

Perpendicular lines = two lines intersecting that form a 90-degree angle (the 90-degree angle must be marked to get the points)

500

How many sides does a regular heptagon have?
