Question

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

Answer 1

Answer:

$y=4x-1$

Step-by-step 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

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