Algebra Problem

100

m = -2    y-int= 8

put in slope intercept form

y = -2x + 8

200

(1,2) and (3, -1)

find slope

-3/2

300

(1,-3) and (4, 0) 

Put in Point-Slope Form

y + 3 = 1(x - 1)

or

y = 1(x - 4)

400

(-2,2) and (3,-8)

Put in Slope Intercept Form

y - 2 = -2(x + 2)

y - 2 = -2x -4

y = -2x - 2

500

Use 2, 3, 4 and 5, and the symbols = and +

It is possible to use each number and symbol once and only once and end up with a true equation; further, you cannot use any number or symbol not given. How can you do this?

3²=4+5

True or False

100

You are currently in an Algebra 1 class.

False

No, of course it's True.

200

The set of all x-values is the x-intercept.

False, it's the Domain

300

Inequalities are expressions compared by symbols such as <, >, and =

False, inequalities cannot be =

400

You would use the inverse operation of subtraction to get the x by itself in this equation

           4x = 8y + 16

False, should divide by 4 not subtract

500
