Slope denoted as m can be calculated from 2 diff. points using the formula: (y2 - y1) / (x2 - x1) = 1 - 12 / 25 - 0 = -11 / 25 Slope-intercept form is y = mx + b. Using a point, 12 = -11/25(0) + b 12 = b y-intercept is 12.
To summarize, slope is -11/25, negative because decreasing trend and y-intercept is 12.
