Find the slope and y-intercept of the line.

y= 4/3x-3

 

y= 6/5x+6

 

14x+4y+24 

 

18x+ 12y+-96

 

14x+4y=28

 

8x+6y=-72 

 

m=3, b=-5

y= 4/3x-3    when it's in this form, the slope is the thing in front of  the x ....(4/3) ..... and the y intercept is what's left after the x...... ( - 3)

 

The second one is just like the first

 

14x+4y=24   the whole objective is to get y by itself on the left side

Subtract 14x from both sides

4y = -14x + 24

Divide both sides by  4

y =(-14/4)x + 24/4      simplify

y = (-7/2)x + 6      and now, the slope is (-7/2) and the y intercept is (6)

 

Haley, you should be able to do the next three.....they're just like this last one

 

Last one  [ easy]

 

m = 3  b= -5

 

Using the form, y = mx +/- b  we have.......

 

y = 3x - 5         that's it!!!!

 

 

 

cool cool cool
