slope 9/2;y-intercept (0,4)

Question

Find the slope-intercept equation for the line with the indicated slope and y-intercept

Answer 1

I think what your asking is: Put the given values in the point slope formula?

 

If so...

 

Use the formula:

y-y1=m(x-x1)

 

Then plug in your values. Use the point (0,4) as x1,y1 and the slope (9/2) as x.

y-4=(9/2)(x-0)

 

Now simplify.

y-4=(9/2)(x-0)

y=(9/2)x+4

y=(9/2)x+4

 

Solution:  y=(9/2)x+4
