What is Domain, Range, Slope?

y=2x+3

y= mx+b where m and b are real number

Here m is the slope

The domain and range of a liner function are all real numbers.

Ex: y=2x+3

The slope is m = 2

The domain and the range are the set of real numbers

200

What is X-intercept, Y-intercept?

y=2x+3

y=mx+b

b is the y-intercept

To find the x-intercept let y=0 and solve for x

Ex: y=2x+3

The y-intercept is 3

The x-intercept is -3/2

How do you write the slope intercept form of an equation? 

8x+4y=16

6x+3y=21

A standard from equation is when it is set up: Ax+By=C

A slope-intercept from equation is when it is set up y=mx+b

8x+4y=16                    6x+3y=21

4y=-8x+16                   3y=-6x+21

y=-2x+4                       y=-2x+7
