Hi,
To find K you will pick a value from the x and then the corresponding Y value. Then we will plug it into the equation that is given y=Kx
Here:
X=25 Y=160
160=k25
(Divide both sides by 25 to isolate K)
K=6.5
Then plug K value into equation
Y=6.5X
Then if you want to check if that is correct you can pick a different point on the table and plug that into the equation to see if you get the same value.
Check:
X=50
Y=6.5x50
Y=320
Answer:
The slope of the line is 3 and the y-intercept is (3/2) three-halves.
Step-by-step explanation:
The data provided is:
X Y
-1.0 -1.5
-0.5 0.0
0.0 1.5
0.5 3.0
The slope of the linear function is denoted by, b and the intercept is denoted by, a.
The formula to compute the slope and intercept are:
Compute the values required in Excel.
Compute the slope and intercept as follows:
Thus, the slope of the line is 3 and the y-intercept is (3/2) three-halves.
Answer:
$18.05

Answer:
I think your right :)
Step-by-step explanation:
The slope can be worked out by the equation:
So with the coordinates (1,2) and (-2,4):
x1 = 1 y1= 2 and
x2 = -2 y2 =4
Note that x1 and y1 use the same coordinate, vice versa with x2 and y2.
Tip: The equation can be y1-y2 and x1-y2 too (have a think why)
So the answer is 2/-3, which is the same as C)
-2/3
