8x+5y=40 How to find a slope

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
