Notice that when x = 0 the value of y is 31/1 so this line "cuts" the y axis at y=31.00000
y-intercept = 62/2 = 31When y = 0 the value of x is 62/3 Our line therefore "cuts" the x axis at x=20.66667
x-intercept = 62/3 = 20.66667Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 31.000 and for x=2.000, the value of y is 28.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 28.000 - 31.000 = -3.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = -3.000/2.000 = -1.500
