Which best names the quantity 1/2 in the linear equation shown?
y = 2x + 1/2
a.) The yintercept ********
b.) The slope
c.) The dependent variable
d.) The xintercept
Kevin plotted a linear equation on a graph with 18 as the yintercept. Which of following could be the equation plotted by Kevin?
a.) 1/2y = 9x + 5
b.) 3x = 6 1/3y
c.) 4x + 18y = 21********
d.) 7x + 2y = 38

(1/3) y = 3 x + 6
multiply both sides by 3
y = 9 x + 18 
^^^^^ for what # ?

Now Wendy, look at your second problem
Kevin plotted a linear equation on a graph with 18 as the yintercept. Which of following could be the equation plotted by Kevin?
a.) 1/2y = 9x + 5
b.) 3x = 6 1/3y <  YES
c.) 4x + 18y = 21******** NO
d.) 7x + 2y = 38 
OK, Thanks.

You are welcome :)
