Answer:

y-4=7(x-1)

Step-by-step explanation:

Hi there!

We are given the slope of the line (7) and the point (1,4) and we need to find the equation in point-slope form.

Point-slope form is given as y- $y_{1}$ =m(x- $x_{1}$ ) where m is the slope and ( $x_{1}$ , $y_{1}$ ) is a point

We have all of the needed information for the equation, but let's first label the values of everything in order to avoid confusion

m=7

$x_{1}$ =1

$y_{1}$ =4

now substitute into the formula:

Hope this helps! :)
