Explanation: The equation of line in slope-intercept form is: y = mx + c where: m is the slope c is the y-intercept
1- getting the slope: To get the slope, we will need two points from the curve. I will choose points (-1,0) and (-2,3) slope = (y2-y1) / (x2-x1) = (3-0) / (-2--1) = -3 The equation now is: y = -3x + c
2- getting the y-intercept: The y-intercept is the value of y at x = 0. From the graph, we can directly get this value. y-intercept = c = -3
Based on the above, the equation of the line is: y = -3x - 3
