<PRE><B>Question 579738</B>
1. Find the slope and the y-intercept of the line. Write fractional answers in lowest terms.

 4y+7x+9= 14+7x
4y=5
y=5/4
The slope is:
The y-intercept is (0, 5/4)

2. Find the slope if it exists of the line containing the pair of points.
 
 (-10.3, 11.8) and (-9.9,4.3)
The slope is:-18.75


3. Find the slope and the y-intercept.
  
 f(x)= -9x-7
 The slope is:-9
 The y-intercept is (0, -7 )


4. Find an equation of the line having the given slope and containing the given point. Express your answer in the form x=a, y=b, or y=mx+b 

 m = -4,(9,0)
 The equation of the line is y=-4x+36


5. Write an equation of the line containing the given point and parallel to the given line. Express your answer in the form y=mx+b
 
 (-4,9);9x=4y+7
 The equation of the line is y=(9/4)x-47/4
