Answer:

A function is a relation in which each input has only one output. In the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2.

What is the slope of 1.5x+4.5y=18
melomori [17]

Answer:

The x intercept is (12,0)

Step-by-step explanation:

1.5x+4.5y=18  Subtract 1.5 x from both sides of the equation

4.5y=-1.5x+18  Divide both sides of the equation by 4.5

4.5y/4.5=-1.5x/4.5+18/4.5

y=-1/3x+4

The slope is -1/3

The y intercept is (0,4)

To find the x intercept, yet y=0 and solve.

1.5x+4.5y=18

1.5x+4.5(0)=18

1.5x=18  Divide both sides of the equation by 1.5

1.5x/1.5=18/1.5

x=12
