How do I work Slope=4, passing through (8,4)

Question

write an equation for the line in slope-intercept form

Answer 1

Hello, Crmessia:

 

You are a lucky person.. I love the Califrnia weather :)

 

I am going to do the problem in a slightly diffrent way.  Using the Point-Slope Form.

 

Now, you might recall that the point slope form is

y-y1= m(x-x1)        where m is the slope and (x1, y1) is the coordinate of the point that the line passes through. In

                              in this case x1=8 and y1=4 and m=4.                  

 

y-4= 4(x-8)           Subtituting

y-4=4x-32             Use the distributive property

  +4     +4             Addinf 4 to both sides

y= 4x-28

 

There you have it.  The same answer done in a diffrent way.  Thanks for posting.

Answer 2

slope=4

y=mx+b

y=4x+b

point (8,4)

4=4(8)+b

4=32+b

4-32=b

b=-28

y=4x-28 for the equation of the line
