8 0

Answer:

the slope is -8/5

Step-by-step explanation:

we need to get the equation in the form

y= mx+b where m is the slope and b is the y intercept

8x + 5y =40

subtract 8x from each side

8x-8x + 5y = -8x +40

5y = -8x+40

divide each side by 5

5y/5 = -8x /5 + 40/5

y = -8/5 x +8

the slope is -8/5 and the y intercept is 8
