y = mx + b

if x = 5, y = 7, and b =10

Plug in

7 = m(5) + 10

-3 = 5m

re-write

5m = -3

 m = -3/5

Answer

slope m = -3/5

Answer: The slope of a line m is -3/5 or -0.6

Step-by-step explanation:

y = mx + b where y = 7, m = ?, x = 5, b = 10.

Substituting for the values of y, m, and b into equation y = mx + b, we have,

7 = m(5) + 10

7 = 5m + 10

Subtracting 10 from both sides, we have,

7 - 10 = 5m + 10 - 10

-3 = 5m

Dividing both sides by 5, we have,

-3/5 = m

m = -3/5 or -0.6
