Which best names the quantity 1/2 in the linear equation shown?

y = -2x + 1/2

a.) The y-intercept ********
b.) The slope
c.) The dependent variable
d.) The x-intercept

Kevin plotted a linear equation on a graph with 18 as the y-intercept. 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 y-intercept. 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 :)
