# Which graph represents the function y = 2x – 4?

We will use the concept of slope and intercept of linear equations in order to plot the curve.

## Answer: The slope of the curve is 2 and its y-intercept is 4.

Let us see how we will concept of slope and intercept of linear equations in order to plot the curve.

**Explanation:**

The slope of the curve is -2 and its y-intercept is -4.

Let us take two points on the line y = 2x - 4 that will help us to plot the graph.

Substitute 0 for x in y = 2x - 4.

y = 2(0) - 4 = -4

So, the line passes through (0, -4)

Substitute 0 for y in y = 2x - 4.

0 = 2x - 4

2x = 4

x = 1/2

So, the line passes through (1/2, 0)

Therefore, the graph y = 2x – 4 of the function is shown below.
