Question

Write the equation of the line thag contains slope of 4 and a coordinate of (3,11)

Answer 1

`y=4x-1`

Explanation:

The point-slope equation of the line is
`y-y_0=m(x-x_0),`

where
`m` is the slope and
`(x_0,y_0)` are the coordinates of the point the line is passing through.

In your case,

`m=4,\\ \\x_0=3,\\ \\y_0=11.`

Thus, the equation of the line is

`y-11=4(x-3),\\ \\y=4x-12+11,\\ \\y=4x-1.`
