| Question 31308:  Hello I need some help with the problems below.  I am not 100% sure how this site works but any help is appreciated.
 1. what is the slope of the line y=5x+7
 at what point does the line y=5x+7 cross the y axis
 2. The y intercept of the line y=20x+500 is 500 how do you show the y intercept as an ordered pair
 3. Find the slope between the two points (1, 5) and (0, 0)

You can put this solution on YOUR website! 1. Slope is rise/run or simply 5/1 or 5 Crosses y-axis at (0,7) or y = 7
 2. for ordered pair (x,y) since x = 0 for the "y intercept" we have (0,500)
 3. Slope = m = (Y2 -Y1) ÷ (X2 -X1)
 m = (0 - 5) ÷ (0 - 1)
 = -5 ÷ -1
 = 5

You can put this solution on YOUR website! If the form of the equation is  , then m is the slope.
  m = 5 That is the slope ----
 It crosses where x = 0. x = 0 is the definition of the y-axis
 
  
  That is where the line crosses the y-axis.
 -----
 (0,500) is the y-intercept as an ordered pair
 It's (x,y), and x is always 0 at the y-intercept
 That's how you find it- you make x = 0.
 ------
 Find the slope between the two points (1, 5) and (0, 0)
 the slope is defined as
 
  Just match up (x[1], y[1]) and (x[2], y[2])
 with (1, 5) and (0, 0)
 the slope is defined as
