A:

Answer:slope: 2y-intercept: -1Step-by-step explanation:The slope is most easily found using two grid intersections. We know that the line crosses the grid intersection (0, -1) at the y-axis. (That is the y-intercept.) And it crosses another one at (1, 1), just above the x-axis in the first quadrant.The slope of the line between these points can be found using the slope formula: m = (y2 -y1)/(x2 -x1) m = (1 -(-1))/(1 -0) = 2/1 = 2The slope can also be found by counting the grid squares of "rise" (2) for each grid square of "run" (1) between those two points or any other convenient points on the line. m = rise/run = 2/1 = 2The slope of the line is 2.__The y-intercept is the point where the line crosses the y-axis. That point is on an unmarked grid line between y = 0 and y = -2. That is, it is halfway between the values 0 and -2, so is y = -1.The y-intercept is (0, -1).
