Question #f41af

Answer 1

`y=4x+23`

After seeing Jim's solution I did a quick search and found this is the 'slope intercept form'

As per Jim's format we have

`4x-y=-23`

Explanation:

This is a variant on the straight line equation of standardised form:
`y=mx+c`

Multiply everything inside the brackets by 4

`y-7=4x+16`

Add `color(red)(7)` to both sides

`color(green)(y-7color(red)(+7)=4x+16color(red)(+7))`

but `-7+7=0`

`y+0=4x+23`

`y=4x+23`
