Question

1. What are the intercepts of the line 3x - 15y = 60?

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

2. What are the intercepts of the line 2x + 4y = 12?

A. x-intercept: 6; y-intercept: -3
B. x-intercept: 6; y-intercept: 3
C. x-intercept: -6; y-intercept: 3
D. x-intercept: -6; y-intercept: -3

Answer 1

x-intercept is when y=0
y-intercept is when x=0

Answer 2

Graph the lines. Or set x = 0 to find the y-intercept. And then set y=0 to find the x-intercept.

Answer 3

Thanks

Answer 4

You can cheat yourself by using www.wolframalpha.com. Or you can solve the problem by setting x = 0 and solving for y, and then setting y=0 and solving for x.

Answer 5

No need to cheat ~ u wont ever learn anythin that way >:l
