1. Subtract 6x from both sides so now you have -2y = -6x + 18
2. Divide everything by -2, then you would have y = 3x - 9
3. The equation is now in slope intercept form so the answer is 3.
The expression represented by 21 increased by twice Gail's height is 21 + 2g
<h3>What are expressions?</h3>
Expressions are mathematical statements that are represented by variables, coefficients and operators
<h3>How to translate the algebraic expression?</h3>
The expression is given as
21 increased by twice Gail's height
Where
g represents Gail's height
So, we have
21 increased by twice Gail's height ⇒ 21 increased by twice g
Twice means 2*
So, we have
21 increased by twice Gail's height ⇒ 21 increased by 2g
increased by means +
So, we have
21 increased by twice Gail's height ⇒ 21 + 2g
Hence, the expression represented by 21 increased by twice Gail's height is 21 + 2g

The slope is 0. All you had to do was put in the calculator for the right answer.
40 feet = 8 foot shadow
So in order to go from 40 to 8 you divide by 5.
So if you have a person who casts a 2 foot shadow, you have to multiply by 5.
Your answer would be 10 feet.
Hope I helped :)
