Answer:
slope -1/2, y-intercept: 1
Step-by-step explanation:
1. y-intercept is the point where the line crosses the y axis. Line crosses y axis at (0,1).
2. Equation of a slope for a line given two points on the line is (y2-y1)/(x2-x1). We'll use (0,1) and (2,0).
3. Set one point as (x1, y1) and the other as (x2, y2). The way you assign them doesn't matter, as long as the 0 and 1 and the 2 and 0 remain together. We'll make (0,1) = (x1, y1) and (2,0) = (x2, y2).
4. Plug in the points for the variables in the equation they correspond to.
5. Solve: (0-1)/(2-0)
=-1/2
