Answer:

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 5/1 so this line "cuts" the y axis at y= 5.00000

y-intercept = 5/1 = 5.00000

Calculate the X-Intercept :

When y = 0 the value of x is 5/7 Our line therefore "cuts" the x axis at x= 0.71429

x-intercept = 5/7 = 0.71429

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 5.000 and for x=2.000, the value of y is -9.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -9.000 - 5.000 = -14.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

Slope = -14.000/2.000 = -7.000
