     up 7 right 1 both positive so slope = 7/1 reduced is 7
4.  slope is 1/3 same process as above 
     up 1 right 3 both positive movement so slope is 1/3 
5.  y = 1/3x - 4    slope intercept form is y = (slope)x + (y-intercept)
     y-intercept is where the graph touches the y-axis

Y∝√x If y=60 when x=36 find,y when x=16
avanturin [10]

Answer:

y = 10√16) = 40

Step-by-step explanation:

This says, "y is proportional to the square root of x."  We are told that y = 60 when x = 36.  Find the formula for this function.  Then, determine what value y will take on when x = 16.

y = k√x  becomes 60 = k√36, or 60 = 6k.  Then k must be 10, and the formula is y = 10√x.

If x = 16, y = 10√16) = 40
