Question

Line m passes through the point (1, 2) and has a slope of 2/5 What is the equation of line m in standard form?

Answer 1

5y - 2x = 8

Explanation:

First off we have to find the y-intercept with : b = y-mx

`b=2-((2)/(5))(1)`

`b=(10)/(5)-(2)/(5)`

`b=(8)/(5)`

now we have the point slope form

`y=(2)/(5)x+(8)/(5)`

Multiply both sides by 5

`5y=2x+8`

Subtract 2x from both sides

`5y-2x=8`
