This is indeed a linear equation. y-4x=9 in standard form is y=4x+9.
"Joint variation<span>" means "directly, but with two or more variables". Thus, we write as follows:
j </span>α gv
<span>
We insert proportionality constant k, to change it to equality.
j = kgv
We solve k,
1 = k (4)(3)
k =1/12
j = gv/12
j = 8(11)/12
j = 22/3</span>
Answer:
b. y=-2x+3
Step-by-step explanation:
find slope by getting any 2 points form the graph
(0,3) (1,1)
m = (y2-y1) / (x2-x1)
m = (1-3) / (1-0) = -2 it means by moving one unit right you need to move 2 unit down
note that it does not matter which points you chose to be second or first
then use slope point equation again it does not matter which point from the slope you use
y - y1 = m ( x - x1 )
y - 3 = -2 ( x - 0)
y = -2x +3
