Question

Which of the following points are on the line given by the equation y = 5x?

Check all that apply.
A. (3,6)
B. (0,1)
C. (3,15
D. (4,2)
E. (-1,-5)
F. (-1,5)

Answer 1

Answer:c and e

Explanation:

I just took the test

Answer 2

C and E

Explanation:

To answer this question, we plug in the X values of the coordinates into the equation to see if they'll give us the corresponding Y value.

(X, Y)

Example:

Y = 5X

6 != 5 * 3

We do this for every coordinate point. If the problem doesn't make sense, it doesn't fall on the line. Let's test every one of these.

B. (0, 1)

1 != 5 * 0

C. (3, 15)

15 = 5 * 3

D. (4, 2)

2 != 5 * 4

E. (-1, -5)

-5 = 5 * -1

F. (-1, 5)

5 != 5 * -1

* For those who don't know, the != is how to say "not equal to" in computer science.
