What is the equation of the line that has a slope of -4 and goes through (-1,6)?

A.
y + 6 = -4(x + 1)
B.
y + 6 = -4(x − 1)
C.
y − 6 = -4(x + 1)
D.
y − 6 = -4(x − 1)

Respuesta :

The equation of the line that has a slope of -4 and goes through (-1,6) is y- 6 = -4(x+1)

Equation of a line in point-slope form

The equation of a line in point-slope form is expressed as:

y i y1 = m(x-x1)

where;

m is the slope

(x1, y1) is any point on the line

Given the following

Slope = -4

point = (-1, 6)

Substitute

y - 6 = -4(x-(-1))

y- 6 = -4(x+1)

Hence the equation of the line that has a slope of -4 and goes through (-1,6) is y- 6 = -4(x+1)
