Question

Write an equation in point-slope form of a line that has a slope of -4 and passes through the point (2, 1)

Answer 1

y= -2x + 9

Step-by-step explanation

y=mx + c where m is slope c is the constant and x and y are the coordinates

so y = 1 x=2 m = -4

so 1 = -4(2)+ c

1= -8 + c

c=9

so

y= -2x + 9
