A line with a slope of 1/2 passes through the point (2, -1). What is the equation of this line?

Question

i need this really quick yall help me please

Answer 1

x-2y= 4

slope = 1/2 = m,

(2,-1) = (h,k) with h=2 and k = -1

use those values and plug them into the standard point slope formula

y-k = m(x-h) to get

y+1 = (1/2)(x-2)

expand, simplify to get

2y +2 = x-2

x-2y = 4
