4. Write a direct variation equation that relates x to y. Then solve. Show both the equation and the solution. If y = 8 when x = 4, find y when x = 5.(Points : 2)

5. Write an equation in slope-intercept form of the line with the given slope and point: slope = 3 and (1, -2).(Points : 1)
y = 3x - 5
y = 3x - 2
y = 3x + 1
y = 3x + 3

4. Write a direct variation equation that relates x to y. Then solve. Show both the equation and the solution. If y = 8 when x = 4, find y when x = 5.(Points : 2) 
      
        
    
5. Write an equation in slope-intercept form of the line with the given slope and point: slope = 3 and (1, -2).(Points : 1)  
       y = 3x - 5
       y = 3x - 2
       y = 3x + 1
       y = 3x + 3

blurbendy · Answer

8 / 4 = 2
y / 5 = 2
10 / 5 = 2
y = 10

5) y = 3x -5 because if you put 1 into x, you get -2
