Answer:

x = -3/10

Step-by-step explanation:

Solve for x by substituting y = 3x into the other equation:

2x - 4y = 3

2x - 4(3x) = 3

Simplify and solve for x:

2x - 12x = 3

-10x = 3

x = -3/10

So, x = -3/10

Answer:

x=-\frac{3}{10}

Step-by-step explanation:

2x - 4y = 3

y = 3x

2x - 4(y = 3x) = 3

2x - 4(3x = 3)

2x - 12x = 3

- 10x = 3

- 10x ÷ - 10 = 3 ÷ - 10

x=-\frac{3}{10}

• The function is a linear function

• The function changes at a constant rate

Step-by-step explanation:

A graph of the function shows it to be a straight line (linear function). Such a function always changes at a constant rate. The line goes downward to the right, so the function is a decreasing function.

___

"changes at a constant rate" and "linear function" are two different ways of saying the same thing: the graph of the function is a straight line.
