Question

The points (0, 0) and (5, 10) lie in the graph of this linear function. Which equation represents the same linear function? A. B. x = 5 C. D. y = 2x

Answer 1

D. y=2x

Explanation:

0x2=0 and 5x2=10. That's really it, simple math

Answer 2

Answer: y = 2x, D.

Step-by-step explanation: We can calculate the slope of the line between these two points: Rise/Run:

Rise: (10-0)=10

Run: (5-0) = 5

Rise/Run = 10/5 = 2

The y-intercept is zero (it is the value of y when x=0, which we are given as (0,0)).

The line between these two points is thus y=2x+0, or

y = 2x. Looks like D.
