Answers:m = -1/2y-intercept = (0,-2)——————-How to find:1) slope (m)using formula rise/run: - The rise is the vertical change between two points while run is the horizontal change. Rise = 1Run = -2m = -1/2using formula y2 - y1 / x2 - x1 (the 1 and 2 are in subscripts)- get two points then substitute in the formula.P1 = (-2,-1)P2 = (0,-2)-2 - (-1) / 0 - (-2)-1 / 2 2) y intercept- Let x be zero.0 + 2y = -42y = -4y = -2 y = (0,-2)
