Question

Determine the y-intercept of the graph of the following function: y=3x+8.

Answer 1

Functions

Given equation:

`\sf{y=3x+8}`

This equation is given to us in slope-intercept. And remember, there's an easy way to find the y-intercept for slope-intercept equations. The way is this:

• the y-intercept is the constant term.

So basically, our task becomes finding the constant term in this function. The constant is 8 - so, that is our y-intercept.

Answer 2

y- intercept = 8

Explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x + 8 ← is in slope- intercept form

with y- intercept c = 8 or in coordinate form (0, 8 )
