Question

if the y intercept of Function R is 3/2 greater than the y intercept of Function J, which equation could represent Function R? A. y= -x + 4.5 B. y= 0.5× + 3 C. y= 3× + 0.5 D. y= 4.5× - 1

Answer 1

The answer is the option C

`y=3x+0.5`

Explanation:

I will assume that the equation of the line in the figure is the function J

Let

R------> the y-intercept of the function R

J------> the y-intercept of the function J

we know that

`R=(3/2)+J` ------> equation A

Observing the graph, the y-intercept of function J is equal to

`J=-1` -----> equation B

Substitute equation B in equation A

`R=(3/2)+(-1)`

`R=0.5`

so

The y-intercept of the function R must be equal to
`0.5`

therefore

The equation
`y=3x+0.5` could represent Function R
