Answer:
The equation of the line in point-slope form is y-1 = 3 ( x + 1)
Equation of a line:
The equation of a line, in point-slope form, is designated using:
y-y0= m( x - x0)
In which the point is given by(x0,y0) and m is the slope.
Slope of the line below is 3 (given in the question).
This means that m = 3
(-1,1)
This means x= -1 and y =1
equation of the line
y - y0 = m( x- x0)
y-1 =m(x-(-1))
y-1=m(x + 1)
substituting the value of m is 3
y-1= 3 ( x + 1)
The equation of the line in point-slope form is y-1= 3 (x + 1)
