Question

2. What is the y-intercept of each equation?2a. y = 6x + 22b. 10x + 5y = 30

Answer 1

The slope-intercept form of a equation is given by:

`y=mx+b`

Where:

m = slope

b = y-intercept

a.

`y=6x+2`

b = y-intercept = 2

b.

`10x+5y=30`

Rewrite the equation in the slope intercept form:

`\begin{gathered} 5y=30-10x \\ y=(30-10x)/(5) \\ y=6-2x \end{gathered}`

b = y-intercept = 6
