First question, 

The point-slope form is: 

\(y-y_1=m(x-x_1)\)

Where \(x_1\) and \(y_1\) are the points (In your question the given point passing through the point (7,1)) x_1 is 7, y_1 is 1

m is the slope

 

so y-1=-4(x-7)

1st choice

 

 

Second question: 

Similar answer,

write it in point-slope form,

y-(-1.4) =1.9(x-4.5)

so,

y+1.4=1.9(x-4.5)

Second choice.
