Find the y intercept of the line y+2x-1=0

Y intercept= 1

Step-by-step explanation:

First you need to put this in slope intercept form (y=mx+b) so heres the steps:

y+2x-1=0 (given)

y-1=-2x (subtract 2x from both sides)

y=-2x+1 (add 1 to both sides)

y=-2x+1 is the y=mx+b form

The y intercept is b so your answer is 1

incomplete question. how do you expect anyone to you when you do not post the question in its entirety?

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
