Question

Write the equation of the line in fully simplified slope-intercept form

Answer 1

y = 3x - 7

Explanation:

Slope - Intercept Form :
`y = mx+b`

`m` = slope

`b` = y - intercept

Slope =
`(rise)/(run)`

=
`\frac3{1}`

=
`3`

So far:
`y = 3x + b`

Plug in a point from the graph, ex. (3,2)

`2 = 3(3) + b\\\\2 = 9 + b\\\\b = -7`

Equation :
`y = 3x - 7`
