Question

What are the interpretations of the line 3x - 15y = 60?

X-intercept y-interception

A: x 20 - y -4
B: x 5 - y 20
C: x -3 - y 15
D: x -4 - y 20

Answer 1

A

Explanation:

To find the intercepts, that is where the line crosses the x and y axes

• Let x = 0, in the equation for y- intercept

• Let y = 0, in the equation for x- intercept

x = 0 : - 15y = 60 ⇒ y = - 4 ← y- intercept

y = 0 : 3x = 60 ⇒ x = 20 ← x- intercept
