Question

What are the x and y-intercepts of the line described by the equation?

2x + 4y = 12.4



Enter your answers, in decimal form, in the boxes.

x-intercept =

y-intercept =

Answer 1

x-int (6.2, 0)

y-int (0, 3.1)

Explanation:

x-intercept is found when y = 0.

y-intercept is found when x = 0.

Step 1: Define equation

2x + 4y = 12.4

Step 2: Find x-intercept

Substitute y for 0.

2x + 4(0) = 12.4

2x = 12.4

x = 6.2

(6.2, 0)

Step 3: Find y-intercept

Substitute x for 0.

2(0) + 4y = 12.4

4y = 12.4

y = 3.1

(0, 3.1)
