Question

I'd really appreciate your help, please no joke answers

Find the distance from (7, -4) to y+3x - 5

Procedure would be apreciated

Image attached and an explaination I don't fully understsand

Answer 1

d= 2√10

Explanation:

y= 3x - 5

3x - y - 5=0

d= | 3* 7 +(-1) * (-4) + (+5) |

________________

`\sqrt{3^(2) } + (-1)^(2)`

d = | 20 | /
`√(10)`

d = 20 /
`√(10)`

d = 2
`√(10)`
