Part a: the origin is (0,0) part b: to plot each point, from the origin you move left or right on the x axis depending on if the number negative or positive, then go up or down, depending on if the number is positive or negative negative numbers go to the left and down positive numbers go to right and up (x,y)
The slope is represented by m and the y-intercept is represented by b in the equation y = mx + b. The slope-intercept form for this would be y = -2/3x + 4.
