Question

Which function could represent the value of a rare coin that increases over time? y=−32x+1y is equal to negative 3 halves x plus 1 y=−23x−7y is equal to negative 2 thirds x minus 7 y=23x+2y is equal to 2 thirds x plus 2 y=32x−6y is equal to 3 halves x minus 6

Answer 1

The function that could represent the value of a rare coin that increases over time is; y = ²/₃x + 2

How to create linear equations?

We want to find which of the equations below could represent the value of a rare coin that increases over time

y = -³/₂x + 1

y = -²/₃x - 7y

y = ²/₃x + 2

y = ³/₂x - 6

Now, the general form of a linear equation in slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

Now, for the equation to be increasing over time, it means the slope must be positive and the y-intercept must also be positive.

Looking at the given options, the only one where slope and y-intercept is positive is y = ²/₃x + 2
