What’s the slope-intercept of an equation of a line goes through (4,-1) and Ian parallel to y=-1/2+2

Answer 1

you probably mean y=-(1/2)x + 2 ???

If so, the slope is -1/2 = m

use the point slope formula

y-h = m(x-k) where (k,h) = (4,-1) and m= -1/2

then

plug in those values to get

y+1 = (-1/2)(x-4)

You can simplify that, multiply by 2 to get

2y+2 = -x +4 or

x+2y = 2
