Question

A function has y-intercept of 4 and a slope of 1/3. Which equation below describes the function? A. y = 1/3x2 + 4 B. y = 1/3x + 4 C. y = 1/3 + x + 4 D. y = 4x + 1/3

Answer 1

B. y = 1/3x + 4

Explanation:

Given a function whose:

• Slope, m = 1/3

,

• y-interept, b = 4

To find the equation that describes the function, substitute the given values into the slope-intercept form of a line.

`y=mx+b`

This gives:

`y=(1)/(3)x+4`

The correct equation is option B.
