You can do 20/2=10 This helps because it is just doing the reverse so you know if you get it both ways that it is correct. Medal please?

Always try to use the inverse operation. Inverse operation is the opposite of your current operation. So if that problem is '2 x 10 = 20' Then you're going to use ' 20 (Divided by) 10' If it equals the first number, which is two, than your answer is correct. hope this helped :)

A line with a slope of -2 is written in the form y=mx+b.

yanalaym [24]

Answer:

b = 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

Here m = - 2 , then

y = - 2x + b ← is the partial equation

To find b substitute (5, - 7 ) into the partial equation

- 7 = - 10 + b ⇒ b = - 7 + 10 = 3
